UR21-MR RFID Scanner


A multi-purpose UHF RFID Scanner with compact design. It is especially suited for retail applications, and it is useful for tracking items in manufacturing and warehousing.

Key Benefits

Counter Scanning

No need to manually read RF tags one after another. Checkout is quick and easy as products scan on the counter.

Fits In Easily

The UR21-MR is compact with thin antenna, so it installs neatly in a small space. You can use it with your existing registers.

The Right Range

A communications range of about 2.6 feet is ideal for point-of-sale registers. You can adjust the range lower to prevent reading products at nearby registers. Or, you can extend the range with a second antenna (Windows).

POS Connectivity

An optional OPOS driver allows you to connect to POS registers and use them with counter scanning.
