Unit RFID

SKU:U031

Description

Unit RFID is a radio frequency identification unit. It is equipped with the MFRC522 chip and operates at a frequency of 13.56MHz. It supports multiple functions such as card reading, card writing, identification, recording, encoding, and authorization of RF cards. Utilizing magnetic field induction technology, it enables non-contact bidirectional information exchange, reading the information from the induction card and verifying it. It can be used in applications such as access control systems, clock-in systems, warehouse inventory management, and vehicle entry and exit registration in residential areas where information verification is required.
