Basic functionality - V400c

Perform basic functions on your terminal, like making a chip or magnetic stripe transaction, and performing refunds.

If the terminal shows an exclamation at the top bar, this means that the terminal holds data that it failed to synchronise with the Adyen payments platform due to lack of an outgoing internet connection.

Make an EMV (chip) transaction

    2. A shopper receipt
