The RFID Card is a 13.56MHz RFID / NFC card with the M5Stack logo.
The main part of the card is composed of chip, coil antenna and card base, and does not carry power itself;
the antenna works by obtaining the radio wave emitted by the reader, and the communication between the reader is realized by radio frequency technology.
Due to its good stability and security, this type of card is widely used in traffic, communication, security and other inductive card management systems that require radio frequency identification.
The Fudan F08 chip built into the proximity card provides long data retention and read and write life while maintaining good sensing performance.
