Doesn`t detect NFC of my Smartphones #35

Hi,

thank you for this cool project. Fits exactly to my needs. It's working successfully with my NFC Badge, Keyring and Stickers. But unfortunately it doesn`t work anymore with my Smartphones (Samsung S6 and Huawei P10 Lite). Whenever creating the user in the Settings (by holding the smartphone to the reader), it always generates a different ID with 7 digits. Each try seems to generate a unique ID.

When testing with the first compiled binary both smartphones worked. But after the last version (or before) it doesn`t work anymore.

Hello,

Are you emulating the RFID tag on your phone? This may be caused by RFID library changes.

As I now, the cheap MFRC522 RFID module is not able to read active tags (=NFC from Smartphones) You have to use the PN532 RFID module (it costs about 4 USD, but requires a different library to access it over SPI/I2C/UART)

If you need a cheap setting, the RC522 is great. But for stronger signals and longer read range, I really recommend the PN532.

I`m not an expert regarding RFID. I heard NFC is similar to RFID. So I simply tried it with one of the first versions and it luckily worked. But if MFRC522 is not designed for that kind of signals, I'll be still happy with keyrings, stickers and what ever kind of tags...

Thanks for the info.
