This feature allows you to create a convenient payment method for your returning customers making it possible for them to pay for future purchases with just one click.
How does it work?
Once your client is finalising their purchase via your e-shop, you can offer them an option to save their card details to commence the future payments with one click only. During an initial payment the customer enters all the required card details and in some cases might be asked to perform 3DS authentication. Next time your customer wants to buy something from your shop, their card details will already be pre-filled. This would lead to the buying process becoming much quicker and more convenient for the customer instead of having to re-enter the card details every single time of purchasing.
From the technical perspective, once the client has given the approval to save their card details, it is our system that actually saves and securely holds the card details and in return generates a token that will be used to refer back to the specific card.
Using the token is secure as the token cannot be reversed back to the card number and it is only valid for the merchant to whom it was originally created for.
Furthermore, even if the card details are saved, it is still possible to make 3DS authentication mandatory for all the one-click payments or for instance ask for the CVV each time the saved card is used for the payment.
