ZVT

Zahlungsverkehrsterminals (Payment terminals) A ZVT interface enables communication between POS software and payment terminal using a ZVT protocol. The payment terminal is connected to the cash register serially (with a cable) or via TCP/IP (Transmission Control Protocol/Internet Protocol), i.e. via LAN/DSL or WLAN network. This allows the payment amount to be transferred from the cash register to the card reader, and the cash register receives the payment status as feedback. Communication via smartZVT is less complex.
