Due to the popularity of RFID technology, the application of identity recognition has become very popular, and the most commonly used for identity recognition is proximity cards or tags. Nowadays, in addition to the identity recognition function achieved through RFID technology, it can also be extended to other applications, such as adding unlocking functions. For example, proximity cards and electronic locks can be used together. The electronic lock can be installed on the door, and then unlock it through card sensing. Therefore, using proximity cards instead of keys to unlock the door will open as long as the card induction is used. This type of technology will be the development trend in the future.

In recent years, many places have begun to install electronic locks, such as hotels, B&Bs, community buildings, etc. You can install electronic locks on your door or room door, then prepare a proximity card and complete the settings. After that, just need to bring the card close to the sensing area, the lock will react and be unlocked successfully. This operation method is very simple, convenient and fast. Traditionally, most people need to rely on keys to unlock their doors, and they must carry their keys with them when they go out. Nowadays, proximity cards can replace keys. You only need to carry a card. Proximity cards are also very convenient in terms of collection. It can also be paired with a back-end management system. When the card is sensed, the data will be automatically stored in the system so that it can be checked in the future to improve security. Therefore, electronic locks designed through RFID technology bring more protection to people's home security.
