This is an incredibly versatile hacking and pen-testing RFID card and one of the most useful cards that it's been our pleasure to source for you all.  This is a single thin card but internally it contains two separate antennas and two separate chips: one low frequency and one high frequency.

The ISO14443A "Magic" MIFARE-compatible S50 UID Changeable chip in this card is a High Frequency RFID credential with some notable features:

  • Designed to Emulate Functionality of a MIFARE 1K Card
  • 4-Byte Changeable UID
  • Operating Frequency: 13.56 MHz
  • 16-bit CRC, parity, bit anti-collision coding, bit counting
  • Data transfer of 106 kbit/s

The T5557 chip in this card is a low frequency 125KHz read/writable transponder which can be programmed to emulate many popular access control system cards.  The T5577 is capable emulating the following access control technologies:

  • HID Prox
  • Indala Flexpass
  • Kantech ioProx
  • Swatch EM41xx
  • Applied Wireless AWID
  • Jablotron
  • Farpointe Data Systems
  • Honeywell NexWatch
  • Noralsy
  • eTag SecuraKey
  • Nedap
  • Viking
  • Presco
  • VISA2000

... and more.

Most field teams opt to program these credentials using a tool such as the Proxmark3, but it is also possible to program and configure T5577 and "Magic" MIFARE S50 UID Changeable credentials with other tools like the Flipper Zero, "Cloner Guns", etc.
