  UR21-MS New!

Ultra-thin stationary scanner that can be installed anywhere

Eliminate long checkout lines

No need to manually read RF tags one after another. Checkout procedure can be completed quickly by just scanning products on the counter.

Ultra-thin antenna avoids catching product and increases usable workspace

The combination of a small controller and a thin antenna eliminates problems in finding an installation location. A dedicated antenna fixture, 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 of products on adjacent checkout counters, the communication range can be adjusted according to needs.
