Question

Hello team, I was able to check the demo for the NFC Mifare classic. The problem with the demo is you need to press a button to open the nfc, then you need to press another to authenticate and finally press another to read. With our app we need to be able to do all this steps without user interaction. Apart from that we need the app to be listening all the time for an incoming nfc tag. That’s why I was asking you last time if there’s something like a listener similar to the one you have with the QR Reader (setHardReaderListener). I would really appreciate if you can help me with this. Thank you.

1、How to read nfc constantly :
Please refer the guide:https://service.telpo.com:8093/index/user/fetfile?key=7lgtEUdTsp5jGvV9

2、This module is non-Android standard NFC SDK, so there is no intent to detect and listen for the card

Here's an example of how to loop check card

Regarding password verification and read/write card operations, it depends on your logic, just like android NFC, you need to write code to verify your password and read/write operations.
