NFC RFID Sticker Advanced Flame Sensor which causes a positive differentialIntroduction : These stickers can be read from and written to using the RC522 RFID Reader and a microcontroller like an Arduino. These can be read by almost any 13. 56MHz RFID NFC reader, but make sure it can handle ISO IEC 14443 Type A cards (the standard NTAG uses) as there are a few other encoding standards. Often used for train bus passes, information sharing, contactless payment, but also found in other systems where a proximity card is desired.
