PCprox 13.56 MHz USB Dongle

The RF IDEAS RDR-7585AKU is a 13.56 MHz RFID reader in a USB dongle form factor. It reads MIFARE cards and tags, delivering data to applications without requiring software installation. The device operates as a plug-and-play keyboard wedge, sending card data directly to the active input field. It supports existing HID iClass and NXP MIFARE badge investments for access control or identity verification.

Suits integrators needing instant card-data entry

This reader suits system integrators and administrators who need to add contactless card reading to existing software without code changes or driver deployment. It is not for buyers who require a long-range reader, a device with Ethernet or RS232 connectivity built in, or support for proximity credentials outside the 13.56 MHz band. It also does not suit applications needing an onboard display or keypad for user interaction.

Read range 2.00–4.00 in with PVC cards

The single specification that decides fit is the typical maximum read range: 2.00" – 4.00" (5.0 – 10.0 cm) with standard PVC ID cards and 1.00" – 1.50" (2.5 – 3.8 cm) with key fobs. This short range demands close presentation, making it suitable for desktop authentication or point-of-sale check-in but unsuitable for hands-free gate access or vehicle identification.

Questions about this item

What comes in the box and is any extra cable or power supply needed?

The USB dongle draws 5 Vdc directly from the USB port so no separate power supply is required.

Which frequency and card types does this model support?

It operates at 13.56 MHz and reads MIFARE cards plus HID iClass badges.

How close must a PVC ID card or key fob be for a reliable read?

PVC ID cards read at 2.00–4.00 inches (5.0–10.0 cm) while key fobs need 1.00–1.50 inches (2.5–3.8 cm).
