Cloning Access Cards to Subdermal RFID Implants
Alex Smith demonstrates cloning building access cards to subdermal RFID/NFC implants, streamlining physical access auditing while eliminating physical cards.
Summary
The Utility of Subdermal RFID Implants for Physical Security
Subdermal RFID and NFC glass implants provide security professionals with an undetectable, hands-free mechanism to store access credentials.
Identifying Card Frequencies and Chipsets
Alex Smith explains distinguishing 125 kHz low-frequency cards (HID Prox, EM4100) from 13.56 MHz high-frequency tokens (Mifare Classic, NFC Type 2).
Cloning Credentials with the Proxmark3
Smith demonstrates using the Proxmark3 to sniff facility reader frequencies, clone facility site codes and card numbers, and write them to T5577 subdermal chips.
Operational Hygiene and Implant Maintenance
The author discusses practical considerations for antenna orientation, coupling efficiency through skin tissue, and re-writing chip sectors.
