This is a MiFare Classic (13.56MHz RFID/NFC) grey Keychain Fob. These chips can be written to, and store up to, 1KB of data in writable EEPROM divided into banks that 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.
