Calling the interface
Following credit card brands are supported: „Samsung“, „Kookmin“, „KEB“, „Hyunday“, „Shinhan“, „BC“, „Lotte“, „VISA“, „MasterCard“, „JCB“, „AMEX“.
Only the currency KRW is supported. This currency is forwarded as WON and no conversion is done. WON is not a ISO 4217 currency and therefore not supported by Computop Paygate. However WON is displayed in the Paygate.Net form because Paygate.Net does not support KRW. Note that KRW has no decimal places according to ISO 4217.
Credit card data (and/or other authorisation data such as mobile no. etc.) is entered into the Paygate.Net form. Sensitive data is not transferred to Computop. Computop retains no credit card numbers or PCNR.
The reference numbers entered (RefNr or TransId) are not printed onto the customer’s bill.
