Unit RFID2

SKU:U031-B

Description

Unit RFID2 is an RFID (Radio Frequency Identification) Unit. It features a built-in WS1850S chip, operating at a frequency of 13.56MHz. It supports multiple functions including card reading, card writing, identification, recording, and encoding and authorization of RF cards. Using magnetic field induction technology, it enables contactless bidirectional information exchange, reading and verifying information from RFID cards. It can be applied in scenarios requiring information authentication, such as access control systems, attendance systems, warehouse goods in/out management, and community vehicle entry/exit registration.

Compared to the previous generation Unit RFID, Unit RFID2 only replaces the read/write IC (RC522 → WS1850S), with no functional differences.
