nexo Definition.

Open standards from the nexo standards association that unify card payment messaging across Europe: the terminal application specification (nexo FAST), the terminal-to-acquirer protocol (nexo Acquirer), and the POS-to-terminal protocol (nexo Retailer), all built on ISO 20022. They are gradually replacing domestic protocols such as CB2A, with a single certification valid in several countries. Large pan-European terminal rollouts (retail, fuel) were the first to adopt them.
