The connector that helps connect external cash register systems (ECR) and a payment terminal when processing refunds from a merchant's account to a cardholder's account. The connector can convert requests from cash register systems entered in a user-friendly format (e.g., CZK 100) into a format the payment terminal understands. Subsequently, it can transform the transaction processing results returned by the terminal into a format comprehensible to the POS system.
Transfer of an amount from the account of the merchant to the cardholder’s account. This transaction is very risky for fraud, so please handle it carefully.
Configuration
POS Connection
IP Address
Destination IP address of terminal (e.g. 10.0.0.5)
