A few years ago. Robotto and i while on a previous door lock quest, attempted to devise a simple nfc alexa peripheral in an attempt to add nfc capabilities to alexa routines for a non nfc smart lock. It worked but was never used. So i thought id share it here so it may be use to someone some day.
Its 4 component. And esp32.a beeper, A pn532 and a bit of cable. Heres the github thingy…
