An RFID lock, also known as a Radio Frequency Identification lock, is a type of electronic lock that uses RFID technology for authentication and access control. RFID technology utilizes radio waves to transmit data wirelessly between an RFID reader and a passive RFID tag.

Available types of RFID:

• Low frequency: 125K Hz
• Mifare: 13.56M Hz (Protocol: ISO 14443A)
• FeliCa: 13.56M Hz [Protocol: ISO 14443A, ISO14443B, ISO0108092(NFC)]

Available 3 modes: 

• Manual close mode (under assigned mode): a programmed RFID card to scan open and scan to lock.
• Automatic close mode (under assigned mode): a programmed RFID card to scan open, and the lock automatically locks after 6 seconds. 
• Public user mode: also known as shared use mode. Locks remain unlocked until locked by a user. The user can select any unused locker and scan an RFID to the lock. The lock will remain locked until unlocked by the same RFID card. Once it unlocks, the RFID card is no longer stored and the locker is available for the next user.
