Using Credit Card Numbers

Please read this chapter before you start exploring our demonstration scenarios.

Do not use real card numbers

When you’re trying out our ecommerce PSP scenario or top up your account for emoney P2P, you can use credit card as a possible payment method. The credit card gateway is a mocked implementation for demonstration purposes, i.e. it does not interact with the outside world and any data entered does not leave the DemoWallet system. Nonetheless, you must not use real credit card numbers.

You can use one of the official test card numbers, e.g.:

VISA 4242 4242 4242 4242

Mastercard 5454 5454 5454 5454

American Express 3782 8224 6310 005

Of course, card expiry dates must be in the future. You can use an arbitrary, valid CVV.

Duplicate handling

Entered payment instrument details, like credit card or bank account details (except CVV), are stored and associated with the corresponding user’s wallet. When the same PAN or IBAN is used in different wallets, this is considered a duplicate.

CoreWallet supports different ways to deal with duplicates. Usually, you do not want different wallets to use the same PAN, as this could indicate fraudulent usage. Therefore this is not allowed by default, but can be changed by configuration.

To ease development, CoreWallet allows to whitelist PANs. Whitelisted PANs will be allowed in multiple wallets even if the restrictive configuration is active.

On the DemoWallet system, we have whitelisted 4242 4242 4242 4242; use this number to avoid any issues with duplicate check errors.
