Credit card payment system introduction
Credit card payment system is used for convenient payment for the charging by using one of the supported credit cards directly.
To be able to pay with a credit card, at least one of the charging stations in payment cluster must be equipped with Payter terminal.
To make credit card payment work, central system and charging stations must be properly configured. All charging stations must be added to the same virtual location and to the same payment cluster.

Payment cluster is a virtual category, created in the central system, because charging stations does not need to be physically on the same network or at the same space. Because it is possible that the user will need to be operating with two charging stations, the charging stations of the payment cluster should still be installed in relatively close vicinity.
The payment cluster contains at least one payment master (charging station with payment terminal - Payter installed) and at least one payment satellite (charging station without Payter terminal).
Payment master will be used for payment in case that user is charging locally (on payment master) or on another charging station in the payment cluster (payment satellite).
User can start charging on payment master or on the payment satellite, however authorization and actual payment can be done only on the payment master charging station.
1.2 Charging Process, Athorization and Payment
Figure 1: LCD screen on the charging station
If user wants to start charging on payment master, he/she will connect car to the free socket, choose Card authorization and swipe the credit card on the Payter terminal installed below the LCD of the charging station.
In case that user wants to start charging on the payment satellite, he/she will connect the car to that charging station and choose Card authorization.
Figure 2: Instructions on the payment satellite
LCD of the charging station will show instructions on how to proceed – to walk to the payment master (number of the charging station will be shown) and type in the shown code of the charging station where the charging will be performed (for example shown on the images, the number is 07-1).
When user approaches the payment master charging station, he/she must press on Pay here button, then choose Charge on another charger and enter code shown on the payment satellite charging station to initiate credit card payment process.
