Understanding CUP payments with WL Sips
The CUP (China UnionPay) card is a means of payment by card hold by more than 150 millions customers across the world (figures in 2018 ), mainly in Asia, allowing you to increase the visibility and attract new international customers.
To pay with a CUP network card, cardholders have to provide their card details, namely:
- the card number;
- the expiry date;
- the visual security code (or security code, referred to as CVV).
|Internet||V||Default payment channel|
|Means of payment|
|Payment upon shipping||X|
|Payment in instalments||X|
|Multicurrency acceptance||X||EUR only|
|Currency settlement||X||EUR only|
The customer selects the CUP means of payment.
They are then redirected to the required information entry page:
The payment ticket is displayed, then the customer returns to your website.
Signing your CUP acceptance contract
In order to offer the CUP means of payment on your website, you have to sign an acceptance contract with Worldline Sweden. Thereafter, you transmit us the contract number for recording in our information system.
Making a CUP payment
You can offer the CUP means of payment through the Sips Paypage interface which directly acts as the payment interface with customers via their web browser.
The only remittance mode available for a CUP transaction is the immediate mode (the transaction remittance is executed at the time of the online payment acceptance).
The diagram below explains the different transaction statuses according to the chosen capture mode:
