DUAL-FREQUENCY RFID KEY FOB

Five rewritable credentials in one compact fob

Four buttons select four independent 13.56MHz CUID tags. The complete fob works as one 125kHz T5577 tag by default.

4 x CUID | 1 x T5577 | 50 x 32 mm

How the five tags are arranged

Four CUID slots: press a button to select its independent 13.56MHz credential.
One T5577 slot: the entire fob responds as the 125kHz credential by default.
Compact body: approximately 50 mm high and 32 mm wide, excluding the key ring.

Hold the fob inside the reader field and keep the required button pressed while detecting, reading or writing that CUID slot.

Compatible readers and tools

Choose the reader that matches the credential you want to operate. PM3X and iCopy-XS support both HF CUID and LF T5577 workflows; PN532 and Chameleon Ultra are for the 13.56MHz CUID slots; the handheld LF cloner is for the 125kHz T5577 credential.

PM3X / Proxmark3 X

HF CUID and LF T5577 read/write workflows.

iCopy-XS

Portable HF and LF credential operations.

PN532 Reader/Writer

13.56MHz CUID reading and writing.

125kHz LF Handheld Cloner

Dedicated operation for the T5577 section.

Chameleon Ultra

13.56MHz CUID workflow through MTools BLE App.

13.56MHz CUID reader and app support

The four CUID slots support direct operation with a compatible NFC-enabled phone. They also work with PM3X / Proxmark3 X, iCopy-XS, and the PN532 RFID & NFC Reader/Writer.

MTools App is supported for compatible mobile NFC workflows. Phone NFC functions can vary by device, operating system and app permissions.

Phone NFC

Operate a selected CUID slot directly with compatible NFC hardware and MTools App.

PM3X and iCopy

Use professional RFID workflows to inspect, read and write a selected CUID credential.

PN532

Use a compatible PN532 reader/writer for supported 13.56MHz CUID operations.

125kHz T5577 reader support

The integrated T5577 credential requires LF-capable equipment. Use PM3X / Proxmark3 X, iCopy-XS, or a dedicated 125kHz LF Key Fob Handheld Cloner.

Important: phone NFC and standard PN532 readers operate at 13.56MHz, so they cannot read or write the 125kHz T5577 section.

Chameleon Ultra + MTools BLE App

The CUID tags also support a Chameleon Ultra workflow. Connect and control Chameleon Ultra through the MTools BLE App, then use the supported read, analyze and write functions for the selected 13.56MHz CUID slot.

Chameleon Ultra does not replace a dedicated 125kHz T5577 writer for the LF section.

Compatibility notes

Confirm the source credential’s protocol and frequency before reading or writing.
