  • Dual-frequency 125 KHz and 13.56 MHz reads both ID and NFC cards
  • Durable metal case protects internal electronics for long-term use
  • Driver-free HID USB interface works on Windows, Mac, Linux, Android and iOS
  • Configurable 40 output formats including 10-hex or 13-digit decimal for EM4100 UID

Dual-Frequency RFID Reader for Access Control

This metal-cased reader scans both 125KHz and 13.56MHz credentials including EM4100 ID cards, 1326 family ISO Prox cards and MF S50 S70 bank cards. It connects via USB and acts as a HID keyboard so no driver is required on Linux, Android, Windows, Mac or iOS. The rugged enclosure suits fixed indoor access points and kiosk installations.

Consistent Reads Across Supported Card Types

The device outputs EM4100 UIDs in up to 40 configurable formats with a maximum 40-bit card number shown in 10H or 13-digit decimal. For 1326 family cards it delivers 40 format options or raw Wiegand bit streams ranging from 24 to 80 bits. Dual-frequency operation removes the need for separate low-frequency and high-frequency readers at each door.

Verify USB Port and Card Compatibility Before Buying

Ensure the host has an available USB-A port or a suitable adapter because the reader draws power and communicates over that single interface. Confirm that the credentials in use are EM4100, 1326 family or ISO14443-A/B types such as MF S50 S70; other chip families and active transponders are not supported. Configuration changes are made with a dedicated config card rather than software.

Questions about this item

Does the metal-case RFID reader draw noticeable power or generate heat when left plugged in all day?

It is a USB HID device with no driver needed, so it draws only the small current a keyboard-style peripheral uses and runs cool during continuous operation.

What must I already have for this reader to work — does it need a separate power adapter or special cable?

Only a free USB-A port on the host; the reader is powered entirely from that port and requires no extra adapter or cable.

Will this dual-frequency reader interfere with an older 125 kHz EM4100 badge system I still use?

It reads both 125 kHz and 13.56 MHz tags simultaneously and outputs the card number in up to 40 selectable formats, so it works alongside existing EM4100 badges without conflict.
