Ratings and reviews

Seems like it works, but when card detected the only thing it does is open the supported application. I don't know, maybe if your phone don't have builtin NFC, this app won't help either.

Unfortunately this app doesn't work with my Samsung J3 phone, locks up on the first page . It knows what external NFC reader is connected.

Doesn't work with the Google Pixel 2 (Android Pie). It crashes when I hold "Service state" option.

What's new

fixed crashes on Android 8.0+
updated usb-serial library
optimized MFRC522/PN532 communication protocol
