[0038] In the credit card holder with an NFC (Near Field Communication) electronic ink screen according to the present utility model, the basis of the NFC module 222 is electromagnetic induction, which mainly involves two aspects: electromagnetic induction and data transmission:

[0039] I. Electromagnetic induction

[0040] When the credit card holder with an NFC electronic ink screen approaches another electronic device with NFC function (such as: an Apple mobile phone or an Android mobile phone with NFC), an electromagnetic field will be established between the credit card holder and the Apple mobile phone;

[0041] In this electromagnetic field, the NFC device (usually the initiator or active device) of the Apple mobile phone or the Android mobile phone will generate a radio frequency field, and this radio frequency field is used to supply power and activate the NFC module 222 of the credit card holder;

[0042] The NFC module 222 of the credit card holder obtains energy from the radio frequency field through electromagnetic induction and uses this energy to drive the circuit inside its NFC chip. In this way, communication can be carried out between the two devices.

[0043] II. Data transmission

[0044] When two NFC devices establish an electromagnetic field and activate each other, they can start to transmit data, and the data is transmitted by modulating and demodulating radio frequency signals;

[0045] When the Apple mobile phone sends a radio frequency field to the NFC module 222 of the credit card, the NFC module 222 of the credit card can obtain energy from it to drive its circuit and display the selected picture signal on the Apple mobile phone on the display interface 221 of the ink screen 23;

[0046] When the Apple mobile phone sends a new radio frequency field to the NFC module 222 of the credit card, the NFC module 222 of the credit card can obtain energy from it again to drive its circuit and change the picture pattern displayed on the ink screen 23.

[0047] The credit card holder with an NFC electronic ink screen of the present utility model combines NFC technology with electronic ink screen technology and applies it to the design of the credit card holder. The ink screen 23 on the credit card holder integrates an NFC module 222, which can be Bluetooth-connected to another NFC device (such as an Apple mobile phone with NFC function). The user only needs to bring the mobile phone with NFC function close to the NFC module 222 of the credit card holder to activate data transmission and achieve wireless data exchange. By transmitting specific data, the user can display various patterns on the ink screen 23 and change the patterns on the credit card holder at will, making the credit card holder more beautiful and personalized.

[0048] The credit card holder with an NFC electronic ink screen of the present utility model not only has the functions of clamping and organizing of a traditional credit card holder, but also can achieve convenient pattern replacement and personalized display through NFC technology and electronic ink screen technology, meeting the user's needs for beauty and personalization. At the same time, due to the short-distance and high security of NFC communication, the credit card holder also has a high guarantee in terms of data transmission and information security.

[0049] The above-disclosed are only the preferred embodiments of the present utility model, and the scope of the patent protection of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the scope of the patent application of the present utility model still fall within the scope covered by the present utility model.
