Unit RFID2

SKU:U031-B

Description

Unit RFID2 is a radio frequency identification unit. It is equipped with the WS1850S 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感应卡 and verifying it. It can be used in applications such as access control systems, attendance systems, warehouse inventory management, and vehicle entry and exit registration in residential areas.

Unit RFID2 has only replaced the read/write IC (RC522->WS1850S) compared to the previous generation Unit RFID, with no functional differences.
