Description

Technical Field

[0001] The utility model relates to an electronic card, and more specifically, to an RFID shopping card. Background Art

[0002] RFID is the abbreviation of Radio Frequency Identification, which is a non-contact automatic identification technology that automatically identifies target objects through radio frequency signals and obtains relevant data. The most basic radio frequency identification system consists of a card core, a reader, and an antenna. The card core is composed of a coupling element and a chip, and each card core has a unique electronic code attached to an object to identify the target object. The reader is a device for reading (or writing) the information of the card core. The antenna transmits radio frequency signals between the card core and the reader.

[0003] Existing shopping cards are basically magnetic stripe card shopping cards, and their production process is as follows: (1) Make a printing template. (2) Select a suitable magnetic card substrate material (usually PVC, etc.) and cut it into standard magnetic card sizes. (3) Place the printing template in the appropriate position and use a color printer to print on the magnetic card substrate. (4) Paste the magnetic stripe on the marked position on the back of the magnetic card substrate: Use a flat brush to evenly apply iron powder on the magnetic stripe to ensure that it covers the entire magnetic stripe. After the iron powder dries, apply a layer of thermosensitive glue on the magnetic stripe, and then place the magnetic stripe on the magnetic card substrate and gently press it to make it adhere.

[0004] Although magnetic stripe card shopping cards can also meet the need for pre-charging, there are the following two defects in the use process:

[0005] (1) For magnetic stripe cards, iron powder needs to be evenly applied on the magnetic stripe. If the coating is uneven, there will be a reading obstacle.

[0006] (2) Magnetic stripes have a service life, and the shopping card cannot be used after the magnetic stripe is demagnetized.

[0007] RFID is a non-contact automatic identification technology that has nothing to do with magnetic stripes and conforms to the trend of technological development. There is a need to apply RFID to shopping cards. Summary of the Utility Model

[0031] The technical solutions of this utility model will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0032] Embodiment 1

[0033] Please refer to Figure 1 , Figure 1 , which is a top view schematic diagram of an RFID shopping card provided for this embodiment. Figure 2 , which is a bottom view schematic diagram of an RFID shopping card provided for this embodiment.

[0034] An RFID shopping card includes a substrate 1. An electronic coding information area 3 is provided on the front surface of the substrate 1. An RFID card core 2 is pasted in the electronic coding information area 3 through pressure-sensitive adhesive. The RFID card core 2 has a unique electronic code. The area outside the electronic coding information area 3 is a first non-electronic information area 4. A second non-electronic information area 5 is provided on the back surface of the substrate 1. The non-electronic information such as text, graphics, or numbers in the first non-electronic information area 4 and the second non-electronic information area 5 is obtained through printing, rubbing, engraving, etc., and the non-electronic information can be directly read visually.

[0035] The preparation method of the RFID shopping card in this embodiment is as follows:

[0036] (1) Make a printing template. (2) Select a suitable substrate material (usually PVC, etc.) and cut it to form substrate 1. (3) Place the printing template in place and use a color printer to print on the front and back of the substrate. (4) Bond the RFID card core 2 to the electronic coding information area 3 on the front of substrate 1 with pressure-sensitive adhesive.

[0037] Example 2

[0038] In Example 1, the non-contact automatic identification of the shopping card is achieved by pasting the RFID card core on the front surface of the substrate with thermal glue. However, since the RFID card core is pasted on the substrate with thermal glue, the top surface of the RFID card core is higher than the top surface of the substrate. Since the user may carry not only shopping cards but also other electronic cards such as bank cards and ID cards, and even if only carrying shopping cards, there may be multiple shopping cards. Moreover, among the user's belongings, there may also be non-flexible items such as nail clippers. When these non-flexible items come into contact with the RFID shopping card, they will contact and rub against the top surface of the RFID card core. Long-term friction may cause reading obstacles when the reader reads the RFID card core.

[0039] Please refer to Figure 3 , Figure 3 which is a schematic diagram of the overall structure of an RFID shopping card provided in this embodiment. Figure 4 which is a schematic diagram of the overall structure of the upper substrate in this embodiment. Figure 5 which is a top view schematic diagram of the lower substrate in this embodiment. Figure 6 which is a bottom view schematic diagram of the lower substrate in this embodiment.

[0040] An RFID shopping card includes an upper substrate 6, a lower substrate 7, and an RFID card core 2. The RFID card core 2 has a unique electronic code. The upper substrate 6 is provided with a through groove 8. The bottom surface of the RFID card core 2 is pasted on the front of the lower substrate 7 with pressure-sensitive adhesive. The back of the upper substrate 6 is attached to the front of the lower substrate 7 as a whole. The RFID card core 2 is located in the through groove 8, and the top surface of the RFID card core 2 is lower than the top surface of the upper substrate 6.

[0041] Through the upper substrate 6, the lower substrate 7, and the through groove 8, and setting the top surface of the RFID card core 2 to be lower than the top surface of the upper substrate 6. Thus, during the user's use process, since the top surface of the RFID card core 2 is lower than the top surface of the upper substrate 6, even if the user carries multiple electronic cards and non-flexible objects, when objects come into contact, the surface in contact with other objects is the top surface of the upper substrate 6 or the back of the lower substrate 7. Since the RFID card core 2 is located in the through groove 8 and its top surface is lower than the front of the upper substrate 6, the friction caused by contact with other items is avoided.

[0042] For the convenience of the reader to read and to make it as thin as possible, the top surface of the RFID chip 2 is only slightly lower than the top surface of the upper substrate 6. Preferably, the height difference between the front surface of the upper substrate 6 and the top surface of the RFID chip 2 is 2 - 8 um, and better results can be obtained.

[0043] Furthermore, the thickness of the upper substrate 6 is 0.13 - 0.18 mm, the thickness of the lower substrate 7 is 0.65 - 0.72 mm, and the thickness of the RFID chip 2 is 120 - 150 um.

[0044] Furthermore, a first non - electronic information area 4 is provided on the front surface of the upper substrate 6. The first non - electronic information area 4 is located outside the through - slot 8, and non - electronic information such as text, graphics or numbers that can be directly read visually is provided on the first non - electronic information area 4; a second non - electronic information area 5 is provided on the back surface of the lower substrate 7, and non - electronic information such as text, graphics or numbers that can be directly read visually is provided on the second non - electronic information area 5.

[0045] Furthermore, the materials of the upper substrate 6 and the lower substrate 7 can be PVC or PET.

[0046] Furthermore, the operating frequency of the RFID chip 2 can be low - frequency 30 - 300 KHZ, high - frequency 3 - 30 MHZ or ultra - high - frequency 300 MHZ - 3 GHZ.

[0047] Furthermore, for the convenience of encapsulation and positioning, an upper positioning hole 9 is provided on the upper substrate 6, a lower positioning hole 10 is provided on the lower substrate 7, and a bonding indication position 11 is provided on the front surface of the lower substrate 7. Through the upper positioning hole 9, the lower positioning hole 10 and the bonding indication position 11, it is ensured that the RFID chip 2 is located at the center of the through - slot 8 after encapsulation.

[0048] The preparation method of the RFID shopping card in this embodiment is as follows:

[0049] (1) Make a printing template. (2) Select suitable substrate materials with different thicknesses (usually PVC, etc.) and cut them to form the upper substrate 6 and the lower substrate 7 respectively. (3) Open the upper positioning hole 9, the through - slot 8 and the lower positioning hole 10 on the upper substrate 6 and the lower substrate 7 respectively, and set the bonding indication position 11 on the front surface of the lower substrate 7. (4) Place the printing template in an appropriate position and use a color printer to print on the front surface of the upper substrate 6 and the back surface of the lower substrate 7.
