Hello, i'm starting a new project that uses NFC. I want to unlock some kind of door with the embedded NFC feature on the Android Smartphone. I was told by an electronic component seller that i can use the cheap RC522 to read the message from the phone and send it to the arduino. But when i search the RC522 on google it was just bassically a RFID reader. My question is it possible to use RC522 as NFC Reader to receive message from a Smartphone?
