USB 125 kHz RFID Dongle

The RF IDEAS RDR-6281AKU is a USB dongle that reads LF 125 kHz proximity credentials. It connects directly to a host computer and requires no external power supply. The reader supports Windows CE, Windows 2000, Windows XP, Windows Vista, Windows 7, Macintosh, the Solaris operating system, Sun Ray thin clients, and Linux.

Mobile Workers and Legacy Badge Systems

This reader suits mobile employees who need badge authentication on laptops or thin clients. It also fits organisations with existing 125 kHz badge populations that want a compact USB form factor. It is not for environments that require a fixed-mount reader with a longer read range or a ruggedised housing for outdoor use.

LF 125 kHz Frequency Only

The single specification that decides fit is the LF 125 kHz operating frequency. The device reads only credentials that operate at this frequency. If your badge stock uses a different frequency technology, this reader will not work.

Questions about this item

How do I install the RDR-6281AKU USB dongle and which step is commonly missed?

Plug the dongle into a free USB port; the step often missed is waiting for the operating system to finish loading the HID keyboard driver before testing with a badge.

What maintenance or replacement will the 125 kHz reader need over time?

No moving parts or batteries are present; only occasional cleaning of the antenna surface with a dry cloth is required.

What is the first limit reached during continuous all-day scanning?

The operating temperature ceiling of 65º C is the first limit encountered under sustained heavy use.
