I made this #rfid reading contraption with #rc522 and #esp32 TTGO T-Display (tried Arduino LCD-keyshield, but it was blocking pins).
It was more complicated than I anticipated (as usual), since the default SPI bus was taken by the display and pins were not even made available, so I had to use the second hardware SPI of the ESP32 (HSPI/VSPI) with alternate set of pins.
This required the use of a different MFRC522 library, which would allow me to use alternate GPIO pins.
Next step: copy-paste
