An RFID lock, also called the IC card lock, is the
electronic lock adopting the radio frequency card as the key. With the
RFID technology, the radio frequency card can be contactless to open the lock
while the old-style contactable card requires the physical contact with
a reader. It is such a technology that the usage of the REID lock is
convenient and safe.
With the technical breakthrough in the field of electron devices, the
radio frequency card can open the lock without batteries or contact.
The RFID technology is the recognition system with the help of the
electromagnetic waves to transmit signals. The identified object itself
consists of devices to receive and transmit electromagnetic waves. This
technology is mainly used for automatic fare collection systems of
buses, ferry and subways, and is applied in the field of the electronic
locking system, access control systems, identification systems and
E-wallets.
Advantages of RFID access control systems for the public areas
RFID control access systems offer the function of tracking people
entering and leaving the space. Once the system is connected with other
information systems, the movement of the certain people can be under
control.
With the RFID lock system, RFID cards of the RFID lock
can be effective or ineffective in real-time operation. At the same
time, the validity of the RFID card is under control because the valid
period of the RFID card can also be set.
The RFID lock can be set to be unlocked automatically in emergency situations. For example, all the RFID locks can be unlocked automatically at the time of the fire.
For home use, the RFID lock is not used to replace the
mechanical lock due to the cost and the traditional concept. As the
implement of the Internet of Things and the Internet Plus, it can be
believed that there are more families willing to use the RFID lock of the RFID access control system.
Besides, it should be noted that the active RFID is safer with higher
costs while the passive RFID card can is easy to be duplicated with low
security and less cost.
The RFID lock can be opened while the card is scanned by the RFID reader. Moreover, the RFID lock can also be opened by the key. The contactless RFID card is very convenient with high induction speed.
With the help of the wireless communication technology, the card of the RFID lock
works when the whole RFID card itself is totally sealed and has no
metallic contact s exposed in the air. Furthermore, the card, the key of
the RFID lock, is also workable under various working conditions.
