Description

[Technical Field]

[0001] Inventor: James Bruce Coleman CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and the benefit of co-pending U.S. patent application Ser. No. 17 / 335,608, filed June 1, 2021, entitled "TRANSACTION CARD INCORPORATING ALUMINUM ALLOYS," which is incorporated by reference as if set forth in its entirety herein. [Background technology]

[0002] Typical transaction cards, such as credit cards, are made from thermoplastic materials such as polyvinyl chloride (PVC) and polyethylene terephthalate (PET). However, plastic cards are susceptible to damage in certain environments. Furthermore, thermoplastic transaction cards can easily bend, break, or cut, thereby damaging the transaction card and rendering it unusable. Furthermore, in the competitive credit card market, where card issuers compete fiercely to attract and retain customers, card issuers choose to issue cards made from different materials to offer a differentiated or premium user experience.

[0003] Some card issuers offer their customers transaction cards that are manufactured from different types of materials, such as metal and / or metal alloys, to provide a superior user experience as well as more durability. As the adoption of metal cards from various card issuers continues to increase, issuers may seek further differentiated ways to provide a superior user experience as well as the durability benefits of metal cards. Summary of the Invention

[0004] Many aspects of the present disclosure can be better understood with reference to the following drawings, in which the components in the drawings are not necessarily to scale, emphasis instead being placed upon clearly illustrating the principles of the present disclosure, and in which like reference numbers indicate corresponding parts throughout the several views.

[Figure 6] 1 is an exemplary flowchart illustrating a process or method according to an example of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0006] Examples of the present disclosure relate to manufacturing transaction cards, such as charge cards, credit cards, or debit cards, from aluminum or aluminum alloys. In one example, aircraft-grade aluminum may be extracted from decommissioned aircraft and repurposed into transaction cards. In this scenario, customers may be provided with metal transaction cards that incorporate parts of a particular aircraft, which can provide a differentiated or premium user experience. For example, a card issuer may sell to customers the heritage, history, and service aspects of the aircraft, as well as the fact that the transaction card issued to the customer is crafted from the aircraft's actual fuselage. Furthermore, in a scenario in which a card issuer offers transaction cards that are co-branded with an airline, such transaction cards can provide a differentiated and premium customer experience. Such an experience may be desirable for card issuers and airlines seeking to attract and retain highly sought-after customers who travel frequently with the airline and utilize co-branded transaction cards for significant amounts of spending.

[0007] When an aircraft reaches the end of its useful life, it is often retired, and the materials utilized to manufacture and maintain the aircraft can be recycled. Certain aircraft have a strong emotional connection to an airline's customer base or to aviation enthusiasts. For example, the Boeing 747™ and its variants have been affectionately referred to by the public as the "Jumbo Jet" or the "Queen of the Skies." Examples of the present disclosure are directed to transaction cards, and methods of manufacturing transaction cards, that incorporate aluminum or aluminum alloys extracted or recycled from retired aircraft, such as the 747.

[0008] Manufacturing transaction cards using aircraft-grade aluminum presents various challenges to card manufacturers. Aluminum is a relatively lightweight metal compared to titanium or stainless steel, making it suitable for use in aircraft. However, lightweight metals utilized in transaction cards may not possess the desired weight or mass for a premium user experience. In one example, the weight of an example transaction card of the present disclosure may range from approximately 13 grams to 19 grams. Thus, an example transaction card of the present disclosure may utilize aluminum recycled from aircraft bodies, but may also include other materials to provide a more substantial, premium feel.

[0009] Furthermore, aluminum is a relatively malleable metal that does not possess a significant degree of elasticity. Therefore, constructing a transaction card entirely or nearly entirely from aluminum or recycled aluminum may result in a card that bends too easily and does not return to its original shape, thereby resulting in a poor user experience. Accordingly, examples of the present disclosure are directed to manufacturing transaction cards that incorporate aluminum or aluminum alloys that may be recycled from aircraft materials, which also possess acceptable weight and elasticity to provide customers with an acceptable user experience.

[0010] Referring now to FIG. 1 , a plan view of a transaction card 100 according to an example of the present disclosure is shown. FIG. 1 illustrates the transaction card 100 having a card surface 204. The transaction card 100 may be constructed with a card body that may include any of the materials disclosed herein. The transaction card 100 may be manufactured with a width 126 and height 128 that conforms to the International Organization for Standardization (ISO) standard ISO 7810 ID-1 card format. The ID-1 card format defines a size of approximately 85.60 x 53.98 mm (3 3 / 8 inches x 2 1 / 8 inches) and rounded corners with a radius of 2.88 to 3.48 mm (approximately 1 / 8 inch). This format further defines a thickness of approximately 0.76 mm. The card format may also allow for a margin of error, such as ±10%, from these dimensions.

[0011] Additionally, the ID-1 format specifies other physical characteristics of cards conforming to the format, including bending stiffness, flammability, toxicity, chemical resistance, dimensional stability, adhesion or blocking, warping, heat resistance, surface distortion, and contamination. The card surface 204 may be printed using ink on a polyvinyl chloride (PVC) surface. The card surface 204 may also be coated with a diamond-like carbon (DLC) coating or lamination and may include other features created by marking, finishing, etching, and / or perforation. The card surface 204 may also be finished with a matte or glossy surface. In some cases, the card surface 204 may be polished to a glossy, highly reflective surface.

[0012] In some examples of the present disclosure, the card surface 204 may be printed directly onto an aluminum layer of the transaction card 100. The transaction card 100 may be constructed using various layers of different materials. In one scenario, an aluminum layer may be utilized as the top layer of the transaction card 100. In another example, a PVC layer may be disposed over the aluminum layer, and the card surface 204 may be printed on the PVC layer.

[0013] The card face 204 may also include an integrated circuit 102, which may include a chip or circuitry that enables communication with a commercial payment terminal. The integrated circuit 102 may be a chip that complies with Europay, Mastercard, and Visa (EMV) standards. The integrated circuit 102 may also comply with different smart card or payment card standards. The integrated circuit 102 may be placed in a cavity formed in the card face 204. The integrated circuit 102 may be positioned on the card face 204 such that one or more contacts associated with the integrated circuit 102 are exposed so that electrical contact can be made with a payment terminal that also implements EMV compliance.

[0014] The card face 204 may also include other features and card information, such as branding, account number, account holder name, loyalty designation (e.g., "Member since 2001"), expiration date, signature, brand name, or other indicia such as legal notices, regulatory compliance messages, phone numbers, URLs, email addresses, trademarks, photos, graphics, bar codes, Credit Card Identification Number (CCID) codes, or any alphanumeric characters.

[0015] 2 shows the card back 205, or the side opposite the transaction card 100 relative to the card front 204. The card back 205 is also known as the back of the transaction card 100. The card back 205 may include a magnetic stripe 206. The magnetic stripe 206 may be attached onto the card back 205. The magnetic stripe 206 may be applied to a transparent laminate layer that covers the printed PVC layer such that the content printed on the PVC layer is visible through the transparent laminate layer.

[0016] For example, the PVC layer can have various text, colors, branding, and other information printed thereon, and a clear laminate layer onto which the magnetic stripe 206 is applied can cover the back PVC layer. The card back 205 can also include a signature panel 210. The signature panel 210 may be etched or milled into the clear laminate surface onto which the magnetic stripe 206 is applied.

[0017] As will be described in subsequent drawings, a transaction card 100 according to the present disclosure may incorporate aluminum, such as aluminum recycled from aircraft. The transaction card 100 may be constructed in a variety of ways using different types of layers to provide a card that complies with ID-1 standards and also provides an acceptable user experience in terms of card weight and rigidity.

[0018] Referring now to Figure 3, an exploded perspective view of a transaction card 100a according to an example of the present disclosure is shown. The transaction card 100a shown in Figure 3 is not drawn to scale and is shown exploded into layers to illustrate the configuration of the various layers utilized to form the transaction card 100a.

[0019] As mentioned above in the description of FIG. 1 , the transaction card 100a may include an integrated circuit 102. The integrated circuit 102 may be located within a cavity formed within the card or on an upper layer of the transaction card 100a. In the example transaction card 100a shown in FIG. 3 , the integrated circuit 102 may be located within a cavity formed in the PVC layer 212. The integrated circuit 102 may be secured to the PVC layer 212 or to a layer beneath the PVC layer 212 using an adhesive to restrict movement of the integrated circuit 102. In some implementations, an adhesive may be selected that insulates the integrated circuit 102 from a metal layer beneath the PVC layer 212. For example, ABLEBOND 931-1T1N1 may be used for this purpose. Furthermore, in various examples, an insulating material may be disposed within a pocket for the integrated circuit 102 to be positioned between the integrated circuit 102 and the transaction card 100a.

[0020] PVC layer 212 represents a layer onto which images, text, branding, and other information may be printed. PVC layer 212 may be printed using an ink printing method. In some examples, raised lettering, etching, engraving, or other printing methods may also be used to print content onto PVC layer 212. For example, laser etching or laser marking may be used to print a logo or other content onto PVC layer 212. PVC layer 212 may have a thickness of approximately 100-150 microns in some examples.

[0021] Adjacent to or directly beneath PVC layer 212 is aluminum layer 214. Aluminum layer 214 represents a layer of aluminum or aluminum alloy, such as aluminum or aluminum alloy, that can be extracted or recycled from retired aircraft. For example, a Boeing 747 aircraft that is finally reaching the end of its useful life may be retired. In some cases, parts and raw materials can be extracted or recycled from retired aircraft. Thus, when certain aluminum alloys, such as 2024-T3 or various other aluminum alloys, are utilized to manufacture the outer skin of an aircraft, these materials can be recycled.

[0022] Furthermore, by recycling aircraft-grade aluminum from actual aircraft, customers may be provided with a transaction card 100 that bears the heritage of the aircraft. In the case of a co-branded transaction card 100 offered in cooperation with an airline, the aluminum may be recycled from decommissioned aircraft utilized by the airline, thereby providing the customer to whom the transaction card 100 is issued with a card that bears the heritage of the actual aircraft used by the airline. In this scenario, these customers are often high-value customers who demonstrate a high level of loyalty to the airline. Therefore, utilizing an aluminum layer 214 recycled from an aircraft in this manner can provide a differentiated and premium user experience.

[0023] The PVC layer 212 and the aluminum layer 214 may be adhered to one another using an adhesive or bonding process to secure the PVC layer 212 and the aluminum layer 214 to one another. The aluminum layer 214 may be formed to a thickness of approximately 100 microns. The thickness of the aluminum layer 214 may be chosen such that additional layers of additional materials may be incorporated into the construction of the transaction card 100 while remaining within the overall thickness requirements specified by the ID-1 card format.

[0024] A stainless steel layer 216 may be utilized on the opposite side of the aluminum layer 214 from the PVC layer 212. The stainless steel layer 216 may be selected to provide additional weight and rigidity to the card. A stainless steel layer 216 having a thickness of approximately 300 microns may be selected. In some implementations, the relative thickness of the aluminum layer 214 to the stainless steel layer 216 may vary. In the example of FIG. 3, a 3:1 ratio of stainless steel to aluminum in terms of thickness is utilized. Because a 3:1 ratio may be utilized, the transaction card 100 uses aluminum but also includes stainless steel, resulting in a card of sufficient weight, rigidity, and resilience. However, other ratios may be utilized to vary the mechanical properties of the transaction card 100. Furthermore, different ratios may be selected if a different aluminum alloy is selected that provides more weight and greater rigidity. For example, an aluminum alloy recycled from a different aircraft may have more weight per square inch and greater rigidity. Thus, in this scenario, more aluminum may be utilized in the transaction card 100.

[0025] A ferrite layer 218 may be utilized on the opposite side of the stainless steel layer 216 from the aluminum layer 214. The ferrite layer 218 may be selected to block or attenuate signals from passing between the integrated circuit 102 and the layer of the transaction card 100a opposite the ferrite layer 218. In other words, the ferrite layer 218 may reduce or suppress electromagnetic interference between the integrated circuit 102 and the antenna layer 220. The ferrite layer 218 may have a thickness of approximately 100-150 microns in some examples.

[0026] The antenna layer 220 may include a near field communication (NFC) or radio frequency identification (RFID) chip that can enable contactless payments in place of the transaction card 100a and communicate with a payment terminal in place of the integrated circuit 102 embedded in the transaction card 100a. The antenna layer 220 may be on the opposite side of the ferrite layer 218 from the stainless steel layer 216. The antenna layer 220 may include a chip with an antenna inlay that provides an antenna electrically connected to the NFC or RFID chip in the antenna layer 220. The antenna layer 220 may have a thickness of approximately 100-150 microns in some examples.

[0027] The back PVC layer 222, or second PVC layer, may have the back surface of the transaction card 100 printed thereon. For example, text, branding, images, and other information may be printed on the back PVC layer 222. Contactless payment logos, phone numbers, legal information, and other information may also be printed on the back surface of the transaction card 100 as required by the transaction card issuer. The back PVC layer 222 may be on the opposite side of the antenna layer 220 from the ferrite layer 218. The back PVC layer 222 may have a thickness of approximately 100-150 microns in some examples.

[0028] The rear laminate layer 224 may be on the opposite side of the rear PVC layer 222 from the antenna layer 220. The rear laminate layer 224 may be the layer on the back side of the transaction card 100 that is exposed to the elements. The rear laminate layer 224 may include a magnetic stripe onto which card information is encoded. The rear laminate layer 224 may also include a signature panel if required by the issuer of the transaction card 100. The signature panel may be etched or printed onto the rear laminate layer 224 to provide a surface that can accept a user's ink or pencil signature. The rear laminate layer 224 may have a thickness of approximately 100 to 150 microns in some examples of the present disclosure.

[0029] 4, an exploded perspective view of an alternative implementation of a transaction card 100b according to an example of the present disclosure is shown. The transaction card 100b shown in FIG. 4 is not drawn to scale and is shown exploded into layers to illustrate the configuration of the various layers utilized to form the transaction card 100b.

[0030] As mentioned above in the description of Figures 1 and 3, the transaction card 100b may include an integrated circuit 102. The integrated circuit 102 may be located within a cavity formed in the card or on an upper layer of the transaction card 100b. In the example transaction card 100b shown in Figure 4, the integrated circuit 102 may be located within a cavity formed in the aluminum layer 314. The integrated circuit 102 may be secured to the aluminum layer 314 or a layer directly below the aluminum layer 314 using an adhesive to restrict movement of the integrated circuit 102. In some implementations, an adhesive may be selected that insulates the integrated circuit 102 from a metal layer, such as the stainless steel layer 316, directly below the aluminum layer 314. For example, ABLEBOND 931-1T1N1 may be used for this purpose.

[0031] In contrast to the example of Figure 3, images, text, branding, and other information can be printed directly onto the aluminum layer 314 rather than onto the PVC layer. The aluminum layer 314 can be printed using an ink printing method that results in the deposition of ink on the aluminum or metal surface. In some examples, raised letter printing, etching, engraving, or other printing methods can also be used to print content onto the aluminum layer 314. For example, laser etching or laser marking can be used to print a logo or other content onto the aluminum layer 314.

[0032] 3, aluminum layer 314 represents a layer of aluminum or aluminum alloy, such as aluminum or aluminum alloy that can be extracted or recycled from a retired aircraft. When certain aluminum alloys, such as 2024-T3 or various other aluminum alloys, are utilized to manufacture the outer skin of an aircraft, these materials can be recycled.

[0033] Furthermore, by recycling aircraft-grade aluminum from actual aircraft, customers may be provided with a transaction card 100b that authentically bears the heritage of the aircraft. In the case of a co-branded transaction card 100b offered in cooperation with an airline, the aluminum may be recycled from retired aircraft utilized by the airline, thereby providing customers to whom the transaction card 100 is issued with a card that bears the heritage of the actual aircraft used by the airline. In this scenario, these customers are often high-value customers who demonstrate a high level of loyalty to the airline. Therefore, utilizing an aluminum layer 314 recycled from an aircraft in this manner can provide a differentiated and premium user experience.

[0034] The aluminum layer 314 may be formed to a thickness of approximately 100 microns. The thickness of the aluminum layer 314 may be selected such that additional layers of additional materials may be incorporated into the construction of the transaction card 100b while remaining within the overall thickness requirements specified by the ID-1 card format.

[0035] The stainless steel layer 316 may be bonded to the aluminum layer 314. The stainless steel layer 316 may be selected to provide additional weight and rigidity to the card. A stainless steel layer 316 having a thickness of approximately 300 microns may be selected. In some implementations, the relative thickness of the aluminum layer 314 to the stainless steel layer 316 may vary. In the example of FIG. 4, a 3:1 ratio of stainless steel to aluminum in terms of thickness is utilized. Because a 3:1 ratio may be utilized, the transaction card 100 uses aluminum but also includes stainless steel, resulting in a card of sufficient weight, rigidity, and resilience. However, other ratios may be utilized to vary the mechanical properties of the transaction card 100b. Furthermore, different ratios may be selected if a different aluminum alloy is selected that provides more weight and greater rigidity. For example, an aluminum alloy recycled from a different aircraft may have more weight per square inch and greater rigidity. Thus, in this scenario, more aluminum may be utilized in the transaction card 100b.

[0036] The ferrite layer 318 may be utilized on the opposite side of the stainless steel layer 216 from the aluminum layer 214. The ferrite layer 318 may be selected to block or attenuate signals from passing between the integrated circuit 102 and the layer of the card opposite the ferrite layer 318. In other words, the ferrite layer 318 may reduce or suppress electromagnetic interference between the integrated circuit 102 and the antenna layer 320. The ferrite layer 318 may, in some examples, have a thickness of approximately 100-150 microns. The antenna layer 320 may include a near field communication (NFC) or radio frequency identification (RFID) chip that can enable contactless payments in place of the transaction card 100b and communicate with a payment terminal in place of the integrated circuit 102 embedded in the transaction card 100b. The antenna layer 320 may be on the opposite side of the ferrite layer 318 from the stainless steel layer 316. The antenna layer 320 may include a chip with an antenna inlay that provides an antenna electrically connected to the NFC or RFID chip in the antenna layer 320. The antenna layer 320 may have a thickness of approximately 100-150 microns in some examples.

[0037] The back PVC layer 322 may have the back surface of the transaction card 100b printed thereon. For example, text, branding, images, and other information may be printed on the back PVC layer 322. When required by the transaction card issuer, a contactless payment logo, phone number, legal information, and other information may also be printed on the back surface of the transaction card 100b. The back PVC layer 322 may be on the opposite side of the antenna layer 320 from the ferrite layer 318. The back PVC layer 322 may have a thickness of approximately 100-150 microns in some examples.

[0038] The rear laminate layer 324 may be on the opposite side of the rear PVC layer 322 from the antenna layer 320. The rear laminate layer 324 may be the layer on the back side of the transaction card 100b that is exposed to the elements. The rear laminate layer 324 may include a magnetic stripe onto which card information is encoded. The rear laminate layer 324 may also include a signature panel, if required by the issuer of the transaction card 100. The signature panel may be etched or printed on the rear laminate layer 324 to provide a surface that can accept a user's ink or pencil signature. The rear laminate layer 324 may have a thickness of approximately 100 to 150 microns in some examples.

[0039] 5, an exploded perspective view of an alternative implementation of a transaction card 100c according to an example of the present disclosure is shown. The transaction card 100c shown in FIG. 5 is not drawn to scale and is shown exploded into layers to illustrate the configuration of the various layers utilized to form the transaction card 100c.

[0040] As discussed above in the description of Figures 1 and 3-4, the transaction card 100c can include an integrated circuit 102. The integrated circuit 102 can be placed in a pocket that can be milled or otherwise formed in the top coating layer 414. The integrated circuit 102 can be secured to the top coating layer 414 or a layer directly below the top coating layer 414 using an adhesive to restrict movement of the integrated circuit 102. In some examples, the top coating layer 414 can comprise a diamond-like carbon (DLC) layer. The top coating layer 414 can be deposited by physical vapor deposition (PVD). DLC coatings can generally be amorphous, although portions of the DLC coating can have a crystalline structure. For example, a DLC coating can include a mixture of forms of carbon, including graphite and diamond. In that regard, DLC coatings can be used to fabricate a DLC-based integrated circuit (DLC)-based integrated circuit (IC)-based integrated circuit (IC). The carbon in the C coating can contain hybridized carbon. The top coating layer 414 can be between 1 micron and 50 microns thick, between 2 microns and 25 microns thick, and between 2 microns and 15 microns thick.

[0041] Images, text, branding, and other information can be printed onto the PVC layer 416. The PVC layer 416 can be printed using an ink printing method that results in the deposition of ink on the PVC surface. In some examples, raised lettering, etching, engraving, or other printing methods can also be used to print content onto the PVC layer 416. For example, laser etching or laser marking can be used to print a logo or other content onto the PVC layer 416.

[0042] Aluminum layer 418 may be adjacent to PVC layer 416. Aluminum layer 418 may also represent the card body. Aluminum layer 418 represents a layer of aluminum or aluminum alloy that may be extracted or recycled from retired aircraft. These materials may be recycled, such as certain aluminum alloys, such as 2024-T3 or various other aluminum alloys utilized to manufacture aircraft skins.

[0043] Aluminum layer 418 may be formed to a thickness that is less than the thickness of the ID-1 card format as defined herein. In the example of Figure 4, the thickness of aluminum layer 418 may be selected so that the bulk of the card body is composed of aluminum, such as aluminum recycled from decommissioned aircraft.

[0044] 3-4, a slot antenna assembly 419 may be utilized that integrates the antenna assembly and near field communication (NFC) or radio frequency identification (RFID) chip into the aluminum layer 418. The slot antenna design utilizes an angled slot cut into the card body, in this case the aluminum layer 418, which acts as the antenna. The design and operation of the slot antenna assembly 419 is further described in U.S. Pat. No. 10,909,436, which is incorporated herein by reference in its entirety.

[0045] The back PVC layer 420 may have the back of the transaction card 100c printed thereon. For example, text, branding, images, and other information may be printed on the back PVC layer 420. When required by the transaction card issuer, contactless payment logos, phone numbers, legal information, and other information may also be printed on the back of the transaction card 100c. The back PVC layer 420 may be on the opposite side of the aluminum layer 418 from the PVC layer 416. The back PVC layer 420 may, in some examples, have a thickness of approximately 100-150 microns.

[0046] The rear laminate layer 422 may be on the opposite side of the rear PVC layer 420 from the aluminum layer 418. The rear laminate layer 422 may be the layer on the back side of the transaction card 100c that is exposed to the elements. The rear laminate layer 422 may include a magnetic stripe onto which card information is encoded. The rear laminate layer 422 may also include a signature panel if required by the issuer of the transaction card 100. The signature panel may be etched or printed on the rear laminate layer 422 to provide a surface that can accept a user's ink or pencil signature. The rear laminate layer 422 may have a thickness of approximately 100-150 microns in some examples.

[0047] 6, a flowchart 600 illustrating an example of manufacturing a transaction card 100 according to an example of the present disclosure is shown. Flowchart 600 depicts a process or method of manufacturing a transaction card 100 according to an example of the present disclosure.

[0048] First, in step 602, a portion of the aluminum or aluminum alloy may be extracted from an aluminum source. In one example, the aluminum may be extracted or recycled from a retired airframe. As discussed above, an aircraft may be retired and the materials used to manufacture the aircraft may be recycled. When certain aluminum alloys are utilized to manufacture the hull or other portions of an aircraft, these materials may be recycled.

[0049] Furthermore, by recycling aircraft-grade aluminum from actual aircraft, customers may be provided with a transaction card 100 that authentically bears the heritage of the aircraft. In the case of a co-branded transaction card 100 offered in cooperation with an airline, the aluminum may be recycled from retired aircraft utilized by the airline, thereby providing the customer to whom the transaction card 100 is issued with a card that bears the heritage of the actual aircraft used by the airline. In this scenario, these customers are often high-value customers who demonstrate a high degree of loyalty to the airline.

[0050] To recycle aluminum from aircraft, some of the aluminum extracted from the aircraft may be cut into smaller sheets to treat and strip paint, contaminants, or other debris. The stripped aluminum can then be heated and sent through rollers to compress the aluminum to a desired thickness. The heating and rolling process may be repeated until the aluminum reaches a desired thickness, such as 100 microns. Once the desired thickness is reached, the aluminum may be annealed or tempered. In one example, the aluminum may be rolled to a thickness of less than 760 microns, which is the thickness specified for ID-1 compliance.

[0051] In step 604, a piece of aluminum having an ID-1 compliant width 126 and height 128 may be cut from the annealed aluminum. The ID-1 compliant sized piece of aluminum may be used as the aluminum layer 214 in the transaction card 100.

[0052] In step 605, the integrated circuit 102 may be placed or disposed within a cavity within the PVC layer 212. The integrated circuit 102 may be an EMV-compliant chip that enables communication with an EMV-compliant payment terminal.

[0053] In step 606, the PVC layer 212 may be attached to the aluminum layer 214. The PVC layer 212 may be pre-printed with card numbers, branding, and other text or images. In some cases, the PVC layer 212 may be printed after it is applied to the aluminum layer 214. The PVC layer 212 may be attached to the aluminum layer 214 using an adhesive or bonding process or glue or adhesive.

[0054] In step 608, the stainless steel layer 216 may be attached to the aluminum layer 214. In one example, the stainless steel layer 216 may be sized to be approximately 300 microns thick with a height 128 and width 126 that is ID-1 compliant. The stainless steel layer 216 and the aluminum layer 214 may be attached to one another using a bonding or joining process or adhesive or bonding agent.

[0055] In step 610, ferrite layer 218 may be attached to stainless steel layer 216. As mentioned above, ferrite layer 218 may be utilized to attenuate or block electromagnetic interference (EMI) between integrated circuit 102 and the NFC or RFID chip in antenna layer 220.

[0056] In step 612, the antenna layer 220 can be attached to the ferrite layer 218. The antenna layer 220 includes an antenna assembly and a wireless integrated circuit for enabling contactless payments. The integrated circuit can be inserted into the antenna layer 220 along with the antenna assembly. The wireless integrated circuit can include an RFID or NFC chip capable of wirelessly communicating with a payment terminal that implements a contactless payment standard. The antenna layer 220 can include a chip with an antenna inlay that provides an antenna electrically connected to the NFC or RFID chip in the antenna layer 220.

[0057] In step 614, the back PVC layer 222 can be attached to the antenna layer 220. The back PVC layer 222 or the second PVC layer can have the card back 205 printed thereon. For example, text, branding, images, and other information can be printed on the back PVC layer 222. When required by the transaction card issuer, contactless payment logos, phone numbers, legal information, and other information can also be printed on the card back 205. The back PVC layer 222 can be pre-printed before being applied to the antenna layer 220, or can be printed after being applied to the antenna layer 220.

[0058] In step 616, the rear laminate layer 224 may be attached to the opposite side of the rear PVC layer 222 from the antenna layer 220. The rear laminate layer 224 may be the layer on the back side of the transaction card 100 that is exposed to the elements. The rear laminate layer 224 may include a magnetic stripe on which card information is encoded. The rear laminate layer 224 may also include a signature panel if required by the issuer of the transaction card 100. The signature panel may be etched or printed on the rear laminate layer 224 to provide a surface that can accept a user's ink or pencil signature. The process may then proceed to completion.

[0059] Although the flowcharts show a particular order of execution, it is understood that the order of execution may differ from that shown. For example, the order of execution of two or more blocks may be scrambled relative to the order shown. In addition, two or more blocks shown in succession may be executed concurrently or with partial concurrence. Furthermore, in some embodiments, one or more of the blocks shown in the figures may be omitted or eliminated.

[0060] Disjunctive language, such as the phrase "at least one of X, Y, or Z," unless specifically stated otherwise, is otherwise understood in the context in which it is generally used to indicate that an item, term, etc. can be either X, Y, or Z, or any combination thereof (e.g., X, Y, Z, X or Y, X or Z, X, Y, and / or Z, etc.). Thus, such disjunctive language is generally not intended to, and should not, imply that an embodiment requires that at least one X, at least one Y, or at least one Z, respectively, be present.

[0061] It should be noted that measurements, amounts, and other numerical data may be expressed herein in a range format. It is understood that there are a number of values ​​disclosed herein, and that each value, in addition to its own value, is also herein disclosed as "about" that particular value. For example, if the value "10" is disclosed, then "about 10" is also disclosed. Similarly, when values ​​are expressed as approximations, by use of the antecedent "about," it will be understood that the particular value forms a further aspect. For example, if the value "about 10" is disclosed, then "10" is also disclosed.

[0062] As used herein, the terms “about,” “approximately,” “at or in the region of,” and “substantially equal” may mean that the quantity or value in question may be an exact value or a value that will produce an equivalent result or effect to that recited in the claims or taught herein. That is, it is understood that quantities, sizes, measurements, parameters, and other quantities and characteristics are not and need not be precise and may be approximate and / or larger or smaller, as necessary, to reflect tolerances, conversion factors, rounding, measurement errors, and the like, as well as other factors known to those skilled in the art to produce an equivalent result or effect. Generally, a quantity, size, measurement, parameter, or other quantity or characteristic is “about,” “approximately,” “at or in the region of,” or “substantially equal,” whether or not expressly stated as such. When “about,” “approximately,” “at or in the region of,” or “substantially equal” is used before a quantitative value, it is understood that the parameter also includes the particular quantitative value itself, unless specifically stated otherwise.

[0063] When a range is expressed, a further embodiment includes from the one particular value and / or to the other particular value. When a range of values ​​is given, it is understood that, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, each intervening value between the upper and lower limit of that range, and any other stated or intervening value in that stated range, is encompassed within the scope of the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the scope of the disclosure, subject to any specifically excluded limit in the stated range. When a stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure.

[0064] For example, where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure; e.g., the phrase "from x to y" includes ranges from "x" to "y," as well as ranges greater than "x" and less than "y." Ranges may also be expressed as upper limits, e.g., "up to about x, y, z," which should be interpreted to include the specific ranges of "about x," "about y," and "about z," as well as ranges "less than x," "less than y," and "less than z." Similarly, the phrase "more than about x, y, z" should be interpreted to include the specific ranges of "about x," "about y," and "about z," as well as ranges "greater than x," "greater than y," and "greater than z." Additionally, where "x" and "y" are numerical values, the phrase "about 'x' to 'y'" includes "about 'x' to about 'y'."

[0065] Such range formats are used for convenience and brevity and, therefore, should be interpreted in a flexible manner to include not only the numerical values ​​expressly recited as the limits of the range, but also all individual numerical values ​​or subranges subsumed within that range, as if each numerical value and subrange were expressly recited. As an example, a numerical range of "about 0.1% to 5%" should be interpreted not only to include the explicitly recited values ​​of about 0.1% to about 5%, but also to include individual values ​​(e.g., about 1%, about 2%, about 3%, and about 4%) and subranges (e.g., about 0.5% to about 1.1%, about 5% to about 2.4%, about 0.5% to about 3.2%, and about 0.5% to about 4.4%, as well as other possible subranges) within the stated range.

[0066] It should be emphasized that the above-described embodiments of the present disclosure are merely possible examples of implementations set forth for a clear understanding of the principles of the present disclosure. Many variations and modifications can be made to the above-described embodiments without substantially departing from the spirit and principles of the present disclosure.
