Unlike 13.56MHz RFID chipsets, 125KHz are much less standardised. It is common to encounter several different data rates with multiple modulation types.

Duplicating 125KHz tags required careful knowledge of each tag type, its modulation and data rates, and a selection of blank tags.

The T5577 chip is a multi-purpose 125KHz RFID emulator, capable of emulating practically every modulation and data-rate combination:

  • Modulation: Biphase, Manchester, FSK, PSK, NRZ
  • Data Rates: RF/2 to RF/128

This enables it to successfully clone almost every 125KHz tag in existence, including:

  • HID Prox (Proxcard, ISOProx, ProxKey)
    (Emulation not supported on multiClass readers, can still clone to rewritable)
  • HID Indala (Motorola Indala)
  • EM400x, EM410x, EM420x
  • Noralsy (KCP3000)
  • Farpointe Pyramid
  • Keri (KC-10X, MT-10X, PKT-10X)
  • Kantech ioProx
  • DoorKing (DKProx) [Not DKProx Long Range]
  • AWID (Low frequency only – CS-AWID, GR-AWID, KT-AWID, PW-AWID)
    (Emulation not supported, can still clone to rewritable)
  • Radio Key (SecuraKey RKKT-01, RKKT-02)
  • Viking
  • Visa2000
  • Schlage IBF iButton (RFID portion only)
