As long as the bank card has a flash payment sign (all chip cards with UnionPay logo) and a contactless chip, namely NFC.

The mobile phone can identify the bank card chip of the bank card through the following steps:

First of all, you must turn on the NFC function of the mobile phone that supports this function, and there must be software in the mobile phone that can recognize the chip card. All three are indispensable. Generally speaking, the software that can identify chip cards in mobile phones is Alipay wallet.

2. Open the software that can read the bank chip card, and take Alipay wallet Android version 9. 1 as an example to open Alipay wallet.

3. Put the bank chip card at 1/2 on the lower part of the mobile phone (NFC is usually attached to the mobile phone case), and Alipay wallet will recognize the bank chip card and display information such as card information, electronic cash, credit card times, recent 10 transaction records, etc.
