Example
[0068] Example 1: Assuming that user A works in a mall, for user A, when in the mall, the calling frequency of the access control NFC card is higher than the calling frequency of the bank NFC card, then user A can set the priority of the access control NFC card higher than the bank The priority of the NFC card allows the electronic device to call the access control NFC card first when in the mall; assuming that user B is not working in the mall, for user B, when in the mall, the calling frequency of the bank NFC card is higher than that of the access control NFC card When calling frequency, user B can set the priority of the bank NFC card to be higher than the priority of the access control NFC card, so that when in the mall, the electronic device can call the bank NFC card first, thereby improving the accuracy of calling the NFC card.
Example
[0069] Example 2: User B’s electronic device is bound to multiple bank cards, that is, the electronic device has multiple bank NFC cards, then user B can set the priority of multiple bank NFC cards according to usage habits, so that the electronic device is calling When using bank NFC cards, the bank NFC card with the highest priority can be used first for transactions. When the balance of the NFC card of the bank with the highest priority is insufficient to respond to the call request, the electronic device can continue to call the NFC card of other banks according to the priority of the bank NFC card, so as to simplify the user's operation and improve the call of the NFC card. Accuracy.
[0070] image 3 It is a flow chart showing a method for invoking a near field communication NFC card according to an exemplary embodiment.
[0071] In a possible implementation, the number of cards to be called is multiple, refer to image 3 In step 103, calling the card to be called may includ...
