This dual-frequency reader offers Bluetooth® low energy technology for reading proximity (125/132 kHz) or contactless smart cards (13.56 MHz) and the Orange Business Services Pack ID mobile credential. The Pack ID credential may be purchased directly from rf IDEAS®. With a dual card reader and Bluetooth low energy module in one device, installation only requires one USB port—freeing additional ports for other peripherals. Four credential configurations (up to three card types and one mobile) accommodate multi-card environments, with the added flexibility of using smartphones for authentication. A user-selectable volume control includes a beeper on/off setting for noise-sensitive areas.
