This NFC repeater (RAM-GDS-CAB-NFCU) acts as an extension (30cm) of the NFC reader on the back of compatible devices giving end users easier access to the scanning function. With easier access to the NFC reader, tablet operators no longer need to remove the device from its docking station to scan — simply install the repeater on your docking station or GDS Tough-Dock and give easy access to programs like Tap To Pay, asset tracking, time management, and more. The repeater extends to 30cm in length and installs on the back of select RAM and GDS Docks.
