PRODUCT GUIDE
Merchant unit
General description
In a configuration where the terminal is not connected to an ECR or PC, the use of a
merchant unit might facilitate the merchant’s operation. It prevents the merchant from
turning the terminal to introduce, for example, the amount the cardholder has to pay.
In this configuration the merchant unit is connected to the C-ZAM/XENTA terminal via a
dedicated interface.
The merchant unit is a slave device of the terminal. This means that all intelligence is in
the terminal and that the merchant unit can be considered as a second display, a second
keyboard and printer of the terminal.
The merchant unit has an integrated printer. This printer has the same technical
specifications as the one attached onto the terminal.
Merchant unit and terminal have a clearly distinguishable design, making it less likely that
cardholders enter their PIN on a merchant unit.
