Everything You Need to Know About RFID Lock

We use RFID technology every day, although sometimes we don't know RFID . For example, when taking public transportation, when using a passport to board the plane or when paying in a store.



A brief introduction to the history of RFID technology.

In 1983, American inventor Charles Walton granted the first patent (US patent) using the term RFID (Radio Frequency Identification). Although many people actually contributed to and helped the invention of RFID technology, Charles Walton obtained 10 patents for RFID-related equipment.


What is RFID lock

RFID is an acronym for radio frequency identification. This refers to a non-contact technology in which the electromagnetic field in the card reader automatically recognizes the digital data encoded in the RFID tag. RFID lock is a key card access lock, commonly used in enterprises, hospitals, hotels, dormitories, gym and other commercial places.Take the RFID locker lock as an example. Its key (usually in the form of a card or fob) is a tag.


The working principle of RFID locking

First, the code of the key card contains the data on the RFID chip contained in the card, and then it is connected to the computer system. Locks, key cards, and computer systems all work together using encrypted data sent over radio frequency.

When you have a card and a certain distance from the lock, the key card, lock and computer system will exchange the required data at this time, and as long as the data matches, you will gain access.


The benefits of RFID lock

The rfid key card replaces the mechanical key, it does not need to touch the lock, and is more convenient than the mechanical key. RFID key cards are more difficult to copy than traditional keys, so RFID locks are more secure. And RFID locks can be installed on a wide range of doors and furniture, suitable for use in many different businesses and applications.
