You may also need to develop on Android, because you need to use our api to listen to the scanning data. And in addition, powering on and off the barcode scanner also requires our SDK API control.

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.

I was testing our app with the T20. The NFC and QR reader did not work with our app. Are this functionalities native to the device or they work with an SDK? Thank you
