NFC payments for the bliksembier beertap firmware work quite good. What you see is an ESP32 with a PN532 NFC reader. The card is a boltcard (NTAG424). Bitcoin, Lightning, LNbits rock!

Finally got boltcard payments for the ESP32 up and running. A new release of BliksemBier that supports boltcard payments is available soon!

Working on a new version of the #plebtap lightning beertap. Now with color touch display.
