  UR21-MR New!

Multi purpose UHF RFID Scanner

Can be installed on existing registers

The combination of a small controller and a thin antenna eliminates problems in finding an installation location. A dedicated antenna mount, which is useful in installing the antenna, is also offered.

No need to worry about reading products on adjacent checkout counters

The communication range is approximately 2.6 feet, which is ideal for the environment for POS registers. To prevent reading RF tags on products on adjacent checkout counters, the communication range can be ADJUSTED according to needs.

By using two antennas, the reading area can be expanded

Two antennas can be connected to one controller, covering a wider range and expanding customer use range.

Connection to POS register becomes easier

For users to use table scanners from a POS application in the same manner as barcode scanners, an OPOS driver*, which helps users connect a table scanner with a POS register, is also available.

* For Windows only
