Flipper-EvilRelay
ISO-DEP (ISO 14443-4) NFC relay for the Flipper Zero. Read a real contactless card on a phone/Evil-Cardputer, relay APDUs over Wi-Fi to an ESP32-C3 bridge, and emulate the card to the reader with the Flipper. Ported from Evil-M5Project.

Could you build this?
No This is an embedded hardware security project that manipulates ISO 14443-4 APDU frames across microcontrollers and radio hardware with strict timing constraints.
What it would actually take: Requires C programming for Flipper Zero's firmware and ESP32-C3 IDF, combined with deep knowledge of NFC physical/data link protocols (ISO-DEP / EMV). The hard part is satisfying strict protocol timeouts (guard times and response delays) while tunneling wireless packets over Wi-Fi without triggering reader transaction aborts.
