I did a lot of coding for these in the UK during early 2000s.

They were pretty nifty for their time, but I guess completely superseded by RFID.

Always annoyed me that it clearly has 2 wires (power/signal + ground).

Same with "TWI" (Two-Wire Interface) , a name that Atmel (now Microchip) uses for I2C bus. There are 3 wires there (SDA, SCL, ground). Or 4, if you count power.
