Designing RFID Implants: Flipping the Bird Opens Doors
Miana Ella Windall chronicles designing and implanting custom subdermal RFID credentials to interact seamlessly with proprietary workplace access control readers.
Summary
The Landscape of Subdermal RFID Implants
Subdermal RFID and NFC microchips allow individuals to store cryptographic credentials, transit passes, and medical identifiers directly beneath the skin.
Overcoming Compatibility Limits in Commercial Implants
When commercial transponders failed to support her employer's proprietary building access control readers, Miana Ella Windall engineered a bespoke implant transponder.
Antenna Design and Biocompatible Packaging
Designing custom subdermal hardware required tuning micro-coil antenna inductance for 13.56 MHz/125 kHz resonance and encapsulating the silicon inside medical-grade biopolymers.
Future Implications for Physical Authentication
Windall shares lessons in amateur hardware prototyping, biological safety protocols, and the ethical future of implanted personal authentication credentials.
