Nayax Cash Only: V00, V01 and V02

V00, V01, and V02 point to different machine-side communication states. Use the code before replacing cables or blaming cellular service.

V00 - no MDB signal

Check MDB cabling, whether cashless is enabled on the vending controller, and whether the reader is set to the correct machine protocol.

The MDB connection exists, but the vending controller has not initialized the reader correctly.

The vending controller has explicitly disabled cashless. Door/service states, pending cash credit, or controller behavior can cause it.
