Denso - UR20 Series
UHF RFID Pad Reader

The Denso UR20 Series UHF RFID Pad Readers are compact readers with separate ultra thin antenna that can be discreetly installed almost anywhere.

The UR21 has been designed for retail POS RFID applications whereby one or two antennas can be installed discreetly under the countertop and has the ability to read through and into the area above multiple items simultaneously, without also reading items on an adjacent counter.

The UR22 is a longer range reader for a broader read area, suitable for deployment in doorways and passages to catch passing traffic. The UR22 allows connection via Ethernet interface.
