[0001] This application claims priority to U.S. Non-Provisional Application No. 17 / 037,148, filed on September 29, 2020, entitled “Detacher For Self-Detaching Tag,” and U.S. Provisional Application No. 62 / 908,551, filed on September 30, 2019, entitled “Detacher For Self-Detaching Tag,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The described aspects relate to a detacher for a security tag used in an electronic article surveillance ("EAS") system. More particularly, to a tag detacher for removing a security tag from an article. Background Art

[0003] Electronic article surveillance ("EAS") systems are designed to prevent unauthorized removal of products from a controlled area. A typical EAS system may include a monitoring system and one or more security tags. The monitoring system may create a monitoring zone at an access point to the controlled area. The security tag may be fastened to a monitored product, such as an item of clothing. If a monitored product enters the monitoring zone, an alarm may be triggered, indicating unauthorized removal.

[0004] Security tags may be fastened to merchandise or other products. It may be desirable to have a system that allows authorized release of security tags while making unauthorized release relatively difficult. Therefore, there is a general need for improved security tags and security tag removal techniques. Summary of the invention

[0005] A simplified summary of one or more aspects is given below to provide a basic understanding of these aspects. This summary is not an extensive overview of all contemplated aspects, and is neither intended to identify key or important elements of all aspects, nor to delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to a more detailed description presented later.

[0006] Example embodiments include an apparatus for unlocking a security tag attached to an article. The apparatus includes an unlocking device configured to provide an unlocking signal or force to the security tag to allow the security tag to be removed from the article. The apparatus further includes an unlocking surface and an alignment feature, the unlocking surface being disposed between the unlocking device and the security tag, the alignment feature being configured to indicate a removal zone corresponding to a source of the unlocking signal, wherein placing the tag in removal allows the unlocking device to provide an unlocking signal or force to the security device to allow the security tag to be removed from the article.

[0007] Another example embodiment includes a method for removing a security tag from a product. The method includes using an unlocking device configured to provide an unlocking signal or force to the security tag to allow the security tag to be removed from the article, wherein an unlocking surface is disposed between the unlocking device and the security tag.

[0018] The following includes definitions of selected terms used herein. The definitions include various examples and / or forms of components that fall within the scope of the terms and can be used in the embodiments. These examples are not intended to be limiting. Further, it will be apparent to those skilled in the art that the present invention can be implemented without these specific details.

[0019] For purposes of this disclosure, directional terms are generally expressed relative to a standard reference system when the systems and devices described herein are installed and oriented for use.

[0020] Throughout the disclosure, the term "substantially" can be used as a modifier of the geometric relationship between elements or the shape of an element or component. Although the term is not limited to a specific change and can cover any change that a person of ordinary skill in the art understands to be an acceptable change, some examples are provided as follows. In one example, the term "substantially" can include a change of less than 10% of the size of an object or component. In another example, the term "substantially" can include a change of less than 5% of the size of an object or component. If "substantially" is used to define the angular relationship between one element and another element, a non-limiting example of the term "substantially" can include a change of 5 degrees or less. These examples are not intended to be limiting and can be increased or decreased based on an understanding of the limitations acceptable to a person of ordinary skill in the relevant art.

[0021] The following is a broad overview that provides added context to aspects and example advantages of aspects of the disclosure.It should be noted that the examples provided in this overview are not intended to be limiting, but are provided for ease of understanding of the disclosure.

[0022] Aspects of the present disclosure relate to a detacher system for removing security tags and that can be used with an electronic article surveillance ("EAS") system. An EAS system in a retail environment can include a monitoring system and at least one security tag or tag attached to an item to prevent unauthorized removal of the item. It should be noted that the terms item, merchandise, and product can be used interchangeably. The monitoring system establishes a monitoring area in which the presence of security tags and / or tags can be detected. For example, the monitoring area can be established at access points (e.g., entrances and exits) to a controlled area. If an item passes through or enters a monitoring area with an active security tag and / or tag, an alarm can be triggered to indicate possible unauthorized removal from the controlled area. Thus, the EAS system can, for example, prevent, indicate, and / or track theft of items from a controlled area. On the other hand, if the item is authorized to be removed from the controlled area, such as when a customer purchases an item at a retail store, the security tag or tag can be removed from the item and / or deactivated to allow the item to pass through the store exit without being detected by the monitoring system and / or triggering an alarm.

[0023] Radio frequency identification ("RFID") systems may also be used in retail environments for inventory management or security-related applications. In an RFID system, a reader sends a radio frequency ("RF") signal to an RFID device. The RFID device responds to the carrier signal with a data signal encoded with information stored by the RFID device. In retail applications, passive RFID tags and / or removable security labels that are sewn or otherwise attached or removably attached to retail items are often used in conjunction with EAS systems.

[0024] Security tags for security and / or inventory systems can be constructed in a variety of configurations. The desired configuration of security tags is generally specified by the nature of the items to be protected. For example, security tags and / or RFID tags can be enclosed in a rigid tag housing that can be fixed to a monitored object (e.g., a piece of clothing in a retail store). The rigid housing generally includes a removable pin or tack that can be inserted through the fabric and placed on the opposite side by a mechanism disposed in the security tag housing. The housing cannot be easily removed from the clothing without destroying the housing and / or the item unless a dedicated removal device is used. The attachment device for EAS security tags includes a variety of different latch mechanisms that are designed to prevent unauthorized personnel from removing and / or retracting the pin from the tag. The excitation required to unlatch the EAS security tag depends on the specific latch mechanism in use. Therefore, various different disassembly units use various means to separate the reusable, removable EAS security tag from the merchandise. The system for unlatching the EAS security tag includes a device that may involve applying force to certain latch assemblies of the EAS security tag. It should be noted that the terms EAS security tag, security label, and security tag are used interchangeably throughout this disclosure. For example, the force may be applied directly by a mechanical element that unlatches the tag (e.g., a probe or hook inserted into the tag) and / or indirectly by a magnet to the latch assembly. Regardless of how the force is applied, the result is that the latch element that was previously engaged with the attachment pin in the tag is disengaged, thereby allowing the tag to be removed from the article. Figure 3a and 3b One example of a security tag that may be used with the present disclosure is described.

[0025] Retail transactions may occur at a point of sale ("POS") station operated by store sales personnel. Store sales personnel may assist customers with the checkout process by receiving payment for the product. If the product includes an EAS element such as a security tag or label, the store personnel will use a dedicated removal device and / or deactivation device to remove the security tag from the purchased product - or in the case of an adhesive label or other RFID device, deactivate the label or RFID device. However, after the purchase is completed, the security tag may require manual removal, which may be time consuming and / or prone to error. In such instances, there is a need to improve the efficiency of the removal device.

[0026] Aspects of the present disclosure relate to a detacher having an external housing that facilitates orienting a security tag relative to a detachment zone or removal area of ​​the detachment device. The external housing provides the advantage of allowing personnel to more efficiently remove security tags from items, such as multitasking during a checkout process or removing security tags from a large number of items. Thus, the present disclosure provides several advantages related to the efficiency of the checkout process.

[0027] Further, the present disclosure is applicable to EAS systems that can be used with mobile point-of-sale transaction (mPOS) systems. In an mPOS system, customers can use their own mobile devices to complete point-of-sale transactions. If security tags are used in an mPOS system, the present disclosure allows users to safely and effectively remove security tags from items after purchase while minimizing the help required from sales personnel. Known detachers are generally difficult to operate, especially for inexperienced users. For example, the magnetic detachers described in the commonly assigned U.S. Patent No. 8,054,185, entitled "Optimization of a Field Profile on a High Field Strength Magnetic Detacher" issued on November 8, 2011, provide advantages in effectively removing tags, and the patent is incorporated herein by reference. However, the present disclosure is directed to a magnetic detacher including an external housing or other aspects that facilitate the orientation of the security tag relative to the detachment zone or detachment area of ​​the detachment device, and is used to provide visual and / or other indications, such as audible or vibration indications that the security tag is authorized to be removed from the item.

[0028] Various aspects are now described with reference to the accompanying drawings. In the following description, for the purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. However, it is apparent that such aspects may be practiced without these specific details. Further, in some cases, well-known methods, procedures, and components or methods that would be understood by those skilled in the art are generally described without specific description so as not to unnecessarily obscure aspects of the present disclosure.

[0029] about Figure 1 and 2 One non-limiting example of an EAS system that may be used with the present disclosure is described to provide context. Figure 1 , an example of an environment 100 (e.g., a retail store) for loss prevention according to aspects of the present disclosure is shown. The environment may include a merchandise 102 having a security tag 104 attached to the merchandise 102. The security tag 104 may be locked (e.g., cannot be removed from the merchandise 102 without damaging the merchandise 102) to prevent unauthorized removal from the merchandise 102. The security tag 104 may include an RFID device 240 configured to send and / or receive RFID signals. The security tag 104 may include a wireless device 250 configured to send and / or receive wireless signals (e.g., Bluetooth, Wi-Fi, NFC, etc.). The RFID device 240 may include an RFID device identifier 241. The wireless device 250 may include a wireless device identifier 251. The security tag 104 may include a controller 290.

[0030] In certain embodiments, environment 100 can include cash register 128 operating in point of sale (POS) area 120. Cash register 128 can complete a sale associated with item 102. Cash register 128 can send a signal to server 140 indicating that the sale associated with item 102 is complete.

[0031] In some embodiments, environment 100 may include server 140 and optional data repository 141. Server 140 may communicate with RFID scanner 112 and / or cash register 128 via communication links 154, 156. Communication links 154, 156 may be wired or wireless communication channels.

[0032] In one aspect of the present disclosure, the environment 100 may include an RFID scanner 112 configured to send and / or receive RFID signals. The RFID scanner 112 may include a communication component 142 configured to communicate with the server 140 via a communication link 154 and / or to communicate with the cash register 128 via a communication link 152. The RFID scanner 112 may include an identification component 144 configured to identify a wireless device 250 associated with the RFID device 240. The RFID scanner 112 may include a release component 146 that sends and / or receives a release signal to the security tag 104. It should be noted that the terms RFID scanner and detacher may be used interchangeably throughout the disclosure. The RFID scanner 112 may include a wireless component 148 that sends and / or receives a wireless signal to the wireless device 250 of the security tag 104. One or more of the communication component 142, the identification component 144, the release component 146, and / or the wireless component 148 may be configured as hardware (e.g., an application specific integrated circuit, an application processor, a field programmable gate array, etc.), software (e.g., instructions stored in the memory 212 executed by a processor of the RFID scanner 112), or a combination thereof. The controller 290 may be configured to send an unlock signal and / or receive a release signal for unlocking the security tag 104. For example, the unlock signal may result in energizing a switch or coil that unlocks or otherwise releases the security tag. In another example, for example, the release signal transmitter 260 may provide a magnetic force that unlocks or otherwise releases the locking mechanism 280 of the security tag 104.

[0033] During operation, prior to a retail transaction, the RFID device 240 of the security tag 104 can be associated with the wireless device 250 of the security tag. In one embodiment, the RFID device identifier 241 can be associated with the wireless device identifier 251. For example, the RFID hardware address of the RFID device 240 or a portion of the RFID hardware address can be associated with the wireless hardware address of the wireless device 250 or a portion of the wireless hardware address. In another embodiment, the serial number of the RFID device 240 or a portion of the serial number can be associated with the serial number of the wireless device 250 or a portion of the serial number. The association can be stored in the server 140 and / or the optional data repository 141. The RFID hardware address can be stored in the RFID device 240 (or a memory in the RFID device 240). The wireless hardware address can be stored in the wireless device 250 (or a memory in the wireless device 250). The serial number of the RFID device 240 and / or the wireless device 250 can be displayed on the security tag 104. The hardware address and / or serial number can be an alphanumeric string. In an alternative example, server 140 may perform a mathematical function (eg, a hash function) on RFID device identifier 241 and / or wireless device identifier 251 and correlate the results.

[0034] In an alternative embodiment, the RFID device identifier 241 can be associated with the release signal 166. For example, the release signal 166 can include a specific waveform. The RFID device identifier 241 can be associated with the release signal 166. The controller 290 can unlock the security tag 104 only in response to receiving the release signal 166 from the RFID scanner 112. Other signals sent to the controller 290 may not unlock the security tag 104.

[0035] In one embodiment, the security tag 104 can be attached to the item 102. The attachment can include a locking mechanism (described below) that prevents unauthorized removal of the security tag 104 from the item 102. The security tag 104 can prevent and / or deter unauthorized removal of the item 102 from the environment 100.

[0036] The detacher system may have a detachment zone and / or limited area or zone that allows for selective detachment of a security tag attached to an article. The detacher provides a tactile and / or visual indication of the location of the detachment zone or "sweep point" of the detacher. Figures 4 to 7 Further explanation of the disassembly zone is described in further detail.

[0037] In some embodiments, a customer 124 may attempt to purchase an item 102. The item 102 may be attached to a security tag 104. For example, a cash register 128 may receive price identification information associated with the item 102 (e.g., a barcode scanned by the cash register 128 or a price tag entered by the clerk 126 and / or the customer 124). In response, the cash register 128 may present the price of the item 102 to the customer 124. The cash register 128 may receive payment (e.g., a credit card, cash, or check) from the customer 124.

[0038] In some embodiments, after providing a purchase or authorization for removal of the security tag, the RFID scanner 112 can send an interrogation signal to the RFID device 240. In response, the RFID scanner 112 can receive a response signal including an RFID device identifier 241 (e.g., an RFID hardware address or an RFID serial number). The RFID scanner 112 can send the RFID device identifier 241 to the cash register 128 via the communication link 152. In response to receiving the RFID device identifier 241, the cash register 128 can associate the sale of the item 102 with the RFID device identifier 241.

[0039] In some variations, the cash register may send a confirmation signal 162 to the RFID scanner 112. The RFID scanner 112 may receive the confirmation signal 162 from the cash register 128 via the communication link 152 and / or from the server via the communication link 156. The confirmation signal 162 may include some or all of the following information: item information for the item 102, the RFID device identifier 241, an indication to unlock the security tag 104 from the item, etc.

[0040] In a non-limiting embodiment, the RFID scanner 112 can identify the wireless device 250 associated with the RFID device 240 based on the RFID device identifier 241. For example, the RFID scanner 112 can send the RFID device identifier 241 to the server 140 via the communication link 154. The server 140 can retrieve the association between the RFID device 240 and the wireless device 250 via the RFID device identifier 241 and send the wireless device identifier 251 to the RFID scanner 112. In another example, the RFID scanner 112 can locally store (in a memory) the association between the RFID device 240 and the wireless device 250. The RFID scanner 112 can retrieve the wireless device identifier 251 from the memory.

[0041] In one aspect of the present disclosure, the RFID scanner 112 may transmit a wireless signal 164 to the wireless device 250 of the security tag 104 based on the RFID device identifier 241 and / or the retrieved wireless device identifier 251. The wireless signal 164 may instruct the wireless device 250 to enable the controller 290 to receive a subsequent and / or simultaneously transmitted release signal 168 for unlocking the security tag 104 from the merchandise 102. The wireless signal 164 may be encrypted. For example, the wireless signal 164 may be encrypted using symmetric or asymmetric encryption. The wireless signal 164 may be encrypted using an Advanced Encryption Standard (AES) algorithm, a Data Encryption Standard (DES) algorithm, an MD5 encryption algorithm, or other suitable encryption algorithms.

[0042] In some aspects, the unlock or release signal transmitter 260 can send a release signal 166 to the security tag 104 to unlock the security tag 104 from the commodity 102. The release signal 166 can be a low frequency signal (e.g., less than 1 MHz). The energy in the release signal 166 can be used by the security tag 104 for the unlocking operation. The release signal 166 can be encrypted. For example, the release signal 166 can be encrypted using symmetric or asymmetric encryption. The release signal 166 can be encrypted using an Advanced Encryption Standard (AES) algorithm, a Data Encryption Standard (DES) algorithm, an MD5 encryption algorithm, or other suitable encryption algorithms.

[0043] refer to Figure 1 and 2 , an instance of the RFID scanner 112 can be configured to send a wireless signal 164 and / or a release signal 166 to the security tag 104. The RFID scanner 112 can include a processor 210 that executes instructions stored in a memory 212 for performing the unlocking functionality described herein.

[0044] In some embodiments, the RFID scanner 112 may include a memory 212. The RFID scanner 112 may include an RFID driver 220 configured to send and / or receive RFID signals via a scanner coil 222. The RFID scanner 112 may include a transceiver 230 configured to send and / or receive wireless signals via a scanner antenna 232. The RFID scanner 112 may include a release signal transmitter 260 configured to send a release signal 166 via a release signal antenna 262.

[0045] The processor 210 may cause the RFID driver 220 to send an RFID signal to the security tag 104 via the scanner coil 222. The RFID driver 220 may energize the scanner coil 222 to send the release signal 166. The scanner coil 222 may include one or more inductors that send or receive electromagnetic signals. The processor 210 may include a release component 146 that causes the release signal transmitter 260 to send the release signal 166 to the security tag 104 via the release signal antenna 262. The processor 210 may include a wireless component 148 that causes the transceiver 230 to send a wireless signal via the scanner antenna 232.

[0046] Additionally, in some non-limiting examples, the security tag 104 may include an RFID device 240 that transmits and / or receives RFID signals via a tag coil 242. The security tag 104 may include a wireless device 250 that transmits and / or receives wireless signals via a tag antenna 252. The security tag 104 may include a locking mechanism 280 that securely secures the security tag 104 to the merchandise 102.

[0047] During operation, in some embodiments, the processor 210, memory 212, wireless component 148, transceiver 230, and / or scanner antenna 232 may receive a confirmation signal 162 from the cash register 128 and / or server 140. The confirmation signal 162 may include an instruction to unlock the security tag 104 for removal from the merchandise 102. The confirmation signal 162 may include the RFID device identifier 241. Alternatively or additionally, after receiving the confirmation signal 162, the RFID driver 220 may send an interrogation signal to the RFID device 240 to receive a response signal including the RFID device identifier 241.

[0048] In some examples, in response to receiving the confirmation signal 162, the processor 210, the memory 212, the identification component 144, the wireless component 148, the transceiver 230, and / or the scanner antenna 232 may identify the wireless device 250 associated with the RFID device 240. In one embodiment, the processor 210, the memory 212, the wireless component 148, the transceiver 230, and the scanner antenna 232 may send a request to the server 140 via the communication link 154. The request may include the RFID device identifier 241. The server 140 may identify the wireless device identifier 251 associated with the RFID device identifier 241. In response, the server 140 may send a response including the wireless device identifier 251 associated with the wireless device 250 to the RFID scanner 112. The RFID scanner 112 may identify the wireless device 250 based on the wireless device identifier 251. In another embodiment, the memory 212 of the RFID scanner 112 may store an association between the RFID device identifier 241 and the wireless device identifier 251. The processor 210 and the memory 212 may identify the wireless device identifier 251 stored in the memory 212 based on the RFID device identifier 241. The RFID scanner 112 may identify the wireless device 250 based on the wireless device identifier 251. Other methods of identifying the wireless device 250 may be used.

[0049] In one embodiment, the processor 210, memory 212, wireless component 148, transceiver 230, and / or scanner antenna 232 may transmit a wireless signal 164 to a tag antenna 252 of a security tag 104. In response to receiving the wireless signal 164, the wireless device 250 may transmit an enable signal 170 to enable the controller 290 and / or the locking mechanism 280 to receive a release signal 166 to unlock the locking mechanism 280.

[0050] In some embodiments, the processor 210, the memory 212, the release assembly 146, and / or the release signal antenna 262 may send the release signal 166 to the locking antenna 292 of the security tag 104. In response to receiving the wireless signal 164 before receiving the release signal 166, the controller 290 may send the unlock signal 172 to the locking mechanism 280. The controller 290 may utilize the electrical energy in the release signal 166 to generate the unlock signal 172. In certain embodiments, the release signal 166 may be a direct current signal or an alternative current signal. The controller 290 may be configured as one or more microprocessors, controllers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gating logic, discrete hardware circuits, and other suitable hardware.

[0051] In some embodiments, the controller 290 may be unable to receive the release signal 166 without previously receiving the wireless signal 164. In other embodiments, the controller 290 may be able to receive the release signal 166 without receiving the wireless signal 164, but be unable to send the unlock signal 172 without previously receiving the wireless signal 164.

[0052] In an alternative embodiment, the controller 290 may receive the release signal 166 only when the waveform 167 of the release signal 166 is substantially the same as the predetermined waveform. In such an example, the processor 210, the memory 212, the release assembly 146, and / or the release signal antenna 262 may send the release signal 166 with the waveform 167 (e.g., amplitude pattern, frequency pattern, phase pattern, modulation, encoding, encryption, etc.). The controller 290 may determine that the waveform 167 of the release signal 166 is substantially the same as the predetermined waveform. As a result, the controller 290 may send the unlock signal 172 to the locking mechanism 280 for unlocking.

[0053] refer to Figure 3a and 3b , the examples of security tags 104 described herein can transition from a locked position 300a to an unlocked position 300b in response to being placed on a removal zone of a removal device (e.g., the RFID scanner 112 described above). In one example, the removal zone can be, for example, on a removal device 312 ( Figures 4 to 7 ), within or near any one or combination of a magnetized area, a removal coil and / or an electromagnetic coil, which allows authorized removal of a security tag (e.g., tag 104) from an article (e.g., article 102) when the tag is placed in the removal zone. In one example, a magnetic force can be applied to the tag 104, which causes the security tag to transition from a locked position 300a to an unlocked position 300b in response to receiving an RFID signal at the RFID device to unlock the security tag. For example, the security tag 104 can receive the wireless signal 164 to enable the RFID device 240 to receive the release signal 166. In response to the release signal 166, the security tag 104 can transition from the locked position 300a to the unlocked position 300b. As described above, an example of a release signal 166 is a magnetic force provided by any one or combination of a magnet, an electromagnet and / or a coil. An example of a location of the release coil within the housing of the detacher 400 is Figure 6 Indicated as reference numeral 430 in the figure.

[0054] It should be noted that the term detachment or detachment zone as used throughout this disclosure is not limited to the force / signal and location on the detacher and / or RFID scanner that provides the detachment force / signal, but may also include an identifier (e.g., identification component 144) or any component associated with the identification and / or release of a security tag. Figure 4 In one example, the removal area 414 can be an area of ​​a remover or scanner 400, which can be, for example, the scanner 112 described above, which provides signal communication associated with any of the above aspects. In one example, the removal area 414 can be, for example, a portion of a larger area or surface 410 ( Figures 4 to 6 ). Throughout the disclosure, the terms removal zone and alignment feature may be used interchangeably. In the foregoing examples, only the placement of the tag 104 in the removal zone 414 allows the release of the tag, while the placement of the tag 104 on the larger area or surface 410 does not allow the release of the tag 104 (e.g., transitioning from the locked position 300a to the unlocked position 300b). The above examples can prevent accidental or unintentional removal of the tag 104 from the article (e.g., if a user removes multiple tags from multiple articles).

[0055] Figure 4 An example of an RFID scanner and / or detacher 400 according to one aspect of the present disclosure is shown. Figure 4 In the example shown, reference Figure 3a and 3b The depicted tag 104 may be placed in a removal zone 414 of the detacher 400. The removal zone 414 may be a portion of a removal surface or surrounding surface 410 disposed between an unlocking device and the security tag 104. Once the tag 104 is authorized to be removed, a release signal and / or force (e.g., a magnetic force) is provided to the tag 104 via the unlocking device within the detacher 400 to release the tag from a locked position (e.g., Figure 3a 300a) to an unlocked position (eg, Figure 3b As shown in the position 300b). Figures 4 to 6 As shown, the removal zone 414 can be a recessed portion of the remover 400. The recessed surface defining the removal zone 414 can be, for example, recessed or otherwise curved downward relative to the larger surrounding surface 410. In one example, the surrounding surface 410 can be substantially flat, and the removal zone 414 curves downward or concavely from it. In one example, as shown in FIG. Figure 4 As indicated, for example, the disassembly area 414 may include a first area 414a, a second area 414b, and a third area 414c ( Figure 5 In one example, for example, the third region 414c can form a depression or other protrusion extending upward from the lowest surface of the second region 414b. In one example, the removal area can be downward from the surrounding surface 410 (e.g., in the example Figure 5The removal zone 414 may extend a distance between 0.3 inches and 0.75 inches, or between 0.4 inches and 0.65 inches, or preferably about 0.5 inches in the negative Y direction indicated by the reference numeral 540. In one example, the diameter of the removal zone may be between 1 inch and 2 inches. In another example, the diameter of the removal zone 414 may be between 1.25 inches and 1.75 inches, or preferably about 1.5 inches. Figure 6 As shown, for example, the disassembly zone 414 can be within a release device (e.g., a release coil or electromagnetic coil) 430 located within the disassembler 400. In the above examples, for example, the disassembly zone 414 and / or the disassembly zone surrounding surface 410 can be molded or otherwise formed as a single component with a cover of the disassembler. The cover of the disassembler can additionally include four sides (e.g., side 416), an inner edge 413 surrounding the disassembly zone surrounding surface, and a rim 412. The combination of features of the cover can provide aesthetic qualities as well as further guide the user or be associated with the disassembly zone 414. In one example, the surrounding surface 410 can be inclined downward toward the disassembly zone 414.

[0056] In one instance, Figures 4 to 7 The detacher shown in can be used, for example, in Figure 6 The disassembler 400 may have similar major dimensions in the indicated X and Z directions. The major outer dimensions of the disassembler may range between 6 inches and 15 inches. In another example, the disassembler 400 may have outer dimensions within a range between 8 inches and 13 inches, and preferably are approximately 10 inches by 10 inches. It should be further noted that the disassembly area 414 may be implemented as an overall larger structure. For example, the surrounding surface 410 may be a portion of a counter or tabletop, such as with a single or multiple disassembly areas 414. In addition, the disassembler 400 and / or the surface 410 and / or the disassembly area 414 may take any shape that is practical for use in a retail or other environment.

[0057] Although not limited to a particular material, the cover and / or outer housing 450 of the disassembly device may be formed of polycarbonate or acrylonitrile butadiene styrene (ABS) plastic. Other examples of materials that can be used to form the disassembly area 414, the surrounding surface 410, and / or the entire cover (e.g., the sides 416, the rim 412, and the inner rim 413) include plastics and other synthetic materials, natural materials such as wood, plant fibers, and / or compressed felt, to name just a few additional examples.

[0058] The aforementioned removal zone 414 allows the user to tactilely and / or visually locate the position where the security tag can be transformed from the locked position to the unlocked position, while demonstrating an aesthetically pleasing device. In addition, because the aforementioned structure does not obstruct or otherwise hinder the tag, and allows for 360 degree alignment of the tag, the aforementioned aspects further improve the efficiency of security tag removal. Therefore, the security of the EAS system can be maintained while eliminating most of the obstacles associated with the ease of use of such systems.

[0059] like Figure 4 and 5 As shown, the detacher 400 can further include an indicator portion, such as an indicator light ring 418. For example, when the tag 104 is properly placed and ready to be removed from the item 102, the indicator light 418 can be illuminated. In one instance, the light 418 can be configured, for example, to illuminate in a particular color (e.g., green) when the tag is ready to be removed from the item. In addition, the light 418 can be configured to change the light duration and / or color depending on the state of the detacher. For example, if the tag is not removable because the user has not properly paid for the item associated with the tag, and / or because the tag is improperly placed or oriented on the detacher 400, the light can be changed to a second color different from the first color (e.g., red) and / or can change duration (e.g., can begin flashing). It should be noted that the above-mentioned indicators are not limited to Figure 5 Light ring 418 is shown. With the benefit of the present disclosure, any single light, series of lights and / or positions can be used to provide the above-mentioned visual indicators. In one example, a light ring can, for example, surround the removal zone 414. In another example, a series of lights in the removal zone surrounding surface 410 can, for example, be configured to flash in a particular pattern or otherwise indicate the location of the removal zone 414. In one example, in conjunction with or in lieu of the above-mentioned visual indications, the device can provide indications via other senses of the user. For example, the remover can vibrate and / or provide an audible indication to provide the status of the device and / or tag.

[0060] It should be further noted that any additional or alternative tactile or visual indicators may be provided to tactilely or visually indicate the location of the removal zone with the benefit of the present disclosure. For example, the removal zone may be a protrusion instead of a recess and / or a protrusion with a recess therein. In another example, the removal zone may be indicated, for example, via a texture or visual difference between the removal zone and the surrounding surface (e.g., ridges, finish, color, or other surface features).

[0061] Figure 7An example of a bottom structure of a detacher 400 according to aspects of the present disclosure is shown. As shown, the detacher 400 may include a bottom housing 400 including a series of contact portions 421a-c configured to contact a surface for the detacher 400 to be placed thereon. In one example, the contact portions 421a-c may be, for example, rubber feet that protrude below the surface of the bottom housing 430. The contact portions 421a-c may, for example, provide a handle to prevent the detacher from being removed from the surface thereon. The bottom housing 430 may, for example, include a cable management portion 432 configured to constrainedly accommodate a cable or series of cables connected to one or more connectors 432b and / or 432c. Cables (not shown) that may be connected to the connectors 432a and / or 432b may provide for connection to an EAS system (e.g., as described with respect to FIG. 1 ). Figures 1 to 2 The system described herein may also be used for signal communication and / or may provide electrical current to power components within detacher 400.
