MR12 Wearable UHF RFID Reader

Hands-free UHF data collector

MR12 is a wearable UHF RFID reader that enables read distance of 9m. Adapting wrist or arm strap, it can be attached to mobile devices by magnetic attachment. With removable battery, MR12 can transmit data via Type C USB or Bluetooth coordinated with app. Compatible with Android and iOS devices, this wearable UHF reader is suitable for warehouse, power inspection, asset management, retail and so on.


Outstanding Reading Performance

Built with a circular polarized antenna which eliminates the limitation of tag orientation, MR12 UHF RFID reader can read UHF tags from 9 meters away, at 900 tags per second at peak performance. If your tag orientation is not consistent and you need a mobile UHF reader that can deal with such task on the move, MR12 is definitely a good choice that delivers superior reading performance and mobility at the same time.


Wireless and Hands-free Freedom

Designed to transmit data via Bluetooth technology, MR12 can easily pair with nowadays popular iOS and Android devices. What’s more, the wearable design of MR12 with optional wrist/arm strap and magnetic handle also enables user to work with freedom of mobility and the ability to read UHF tags comfortably while keeping both hands free.


Durability and Safety by Design

The ruggedized design of MR12, including industrial-class protection with IP65 sealing and 1.2 meters drop resistance, ensures that MR12 can prevent the infiltration of dust and raindrop and withstand the impact of everyday drops and bumps in all kinds of working environments. IP65 sealing also means that MR12 can operate safely in any environment filled with inflammable and explosive air or gas
