The Hackitsune ESPKey is a compact, inline Wiegand interception and replay module built for professional access control testing and diagnostics. Designed to sit transparently between a reader and panel, ESPKey works with systems using standard 5V Wiegand signalling including card, fob, keypad, and many biometric readers that output Wiegand downstream. Once installed, it can log credential bitstreams in transit, store them in non-volatile memory (up to ~80,000 depending on format), and replay them in via its built-in Wi-Fi web interface. Small enough to fit behind most readers, powerful enough to demonstrate real-world vulnerabilities.
