This is a blank 13.56MHz RFID/NFC card - often used for train/bus passes but also found in other systems where a proximity card is desired. The tag contains a small RFID chip and an antenna, and is passively powered by the reader/writer when placed a couple inches away. Features: These can be read by almost any 13.56MHz RFID/NFC reader but make sure it can handle ISO/IEC 14443 Type a cards as there are a few other encoding standards.These chips can be written to & store up to 1 KB of data in writable EEPROM divided into banks, and can handle over 100,000 re-writes.There is also a permanent 4-byte ID burned into the chip that you can use to identify one tag from another - the ID number cannot be changed.
