UR21-MS RFID Scanner

UR21-MS scanner

Ultra-thin, stationary scanner that can be installed anywhere. It is especially suited for retail applications.

The antenna and controller are compact and virtually unlimited in where they can be used.

More Productivity

Quicker Checkout, Shorter Lines

No need for manual scanning—RF tags are captured instantly on the counter.

Avoids Catches

Ultra-thin (5 mm) antenna prevents snags to make scanning efficient and fast.

The Right Range

The communications range (approximately 2.6 feet) is ideal for point-of-sale registers. You can also adjust the range lower to prevent reading products at nearby registers.
