CB2A Definition.

French card messaging protocol between the point of acceptance (POS terminal, payment server) and the acquirer, derived from ISO 8583: authorization requests and end-of-day batch upload files. Each acquirer maintains its own implementation, which complicates terminal certification. It is gradually migrating to the European nexo standards, based on ISO 20022.
