125kHz and 13.56MHz Dual Frequency RFID Reader Writer NFC Reader Module
1. Support 125Khz and 13.56Mhz
a) 13.56Mhz, ISO 14443A & card
b) 125Khz, EM card and TK card, read card ID only.
C) Support read & write 13.56Mhz: The chip integrates instructions such as automatic card searching,
reading, writing, initializing e-wallet, adding value, reducing
value, and checking balance, etc. The user uses the command set to
simply operate the card.
2.Dual frequency antenna integration all in one.
3.Low power dissipation: ≤30uA
4.Support serial port TTL communication
5.Small size, 62x34.5mm
6.UART interface
7.Can be customized according to client's request.
