Payment method remarks

• Methods PayU - payment card and PayU - secure form enable card payments and differ only with the way the card data is entered. Should not be configured both at once.
• In case PayU - bank list method is switched on, the following payment types are removed from the list: cards if PayU - payment card or PayU - secure form is on, Blik if PayU - Blik is on, installments if PayU - installments is on, Klarna if Payu - Klarna is on, Twisto if PayU - Twisto is on, PayPo if PayU - PayPo is on.

• Even if PayU - payment card, PayU - secure form, PayU - Blik, PayU - installments, PayU - Klarna, PayU - Twisto and PayU - PayPo are on, they may be not visible in case they are not configured on your POS in PayU system or if the amount is outside min-max range for the given payment type.
