125 kHz HID Prox desktop reader

The RF IDEAS RDR-6081AK0 reads 125 kHz HID Proximity cards at 1.0 to 3.0 inches depending on card type and environment. It connects through USB, RS-232 or Ethernet and draws power from USB, PoE or several serial power options. The unit measures 3.37 by 1.99 by 0.59 inches and weighs 0.25 lb. It is suited for organisations that want staff to reuse existing building-access badges for logical login or time-and-attendance.

USB CDC virtual COM and flash configuration

The USB interface presents a CDC virtual COM port so the reader appears as a serial device without extra drivers. On-board flash memory stores output formatting, keystroke emulation or prefix/suffix strings set once by the administrator. A beeper and LED give immediate feedback on each read. These features remove the need for manual data entry and let the device fit into legacy or web-based applications with minimal software changes.

Read-range and temperature limits

Typical read range tops out at 3.0 inches, so the badge must be presented close to the housing. Operating temperature spans -22 to 150 °F and storage reaches -40 to 185 °F with 5 to 95 % non-condensing humidity. The reader does not support 13.56 MHz credentials, MIFARE, iCLASS or NFC phones. Buyers needing longer range, dual-frequency operation or mobile-credential support should look elsewhere.
