It is an easy to use Sensor ID 125Khz Card Reader. Quick to read RFID tags. Plug and play, no extra driver needed. Used in many RFID application systems, such as personnel identification, logistics, access control, conference system, anti-counterfeiting system and industrial production process control.

The RFID USB Reader is a simple to use, USB to serial base unit for the ID-3LA, ID-12LA, and ID-20LA readers. 

The MFRC522 operates in the frequency range of 13.56 MHz and uses the principle of modulation and demodulation to interact with the RF proximity card. This unit can perform the function of the card reading and writing device, to identify and record various information on the card, to encode and authorize an RF card.

The RFID Smart Lock can provide good security protection for your personal items, in addition to protecting your privacy. It can also improve the safety of children at home, prevent them from being free to open drawers or cabinet doors.
