This electronic card-based lock system is the word RFID refers to Radio Frequency Identification. RFID is a tracking system that uses intelligent bar codes to track items in a store. RFID finds many applications including Access management, tracking goods, Tracing human beings and animals, Toll collection, Noncontact payment, etc.

In the kit, an electronic card-based lock system Radio-frequency identification (RFID) based access-control system allows only authorized persons to enter a particular area of an establishment. The authorized persons are provided with unique tags, using which they can access that area. This kit is an effort to design a prototype security system based on RF-ID to directly know the person and check out the authentication to open a gate.

In the electronic card-based lock system kit there are different types of valid RF ID cards for a prototype that can be used to open the gate. As soon as the card is swapped, the RF-ID reader will read the tag of the RF-ID and send it to the controller. Its authentication will be done by the microcontroller. If the tag matches the database, then the gate will be opened automatically.
