One Click service gives a possibility to make a purchase without entering the full card data to confirm payment (only CVC2 code must be entered) for loyal customers.

The merchant maintains its database of customers, giving them an unique number (CustomerNumber), while the IPS Assist stores the encrypted credit card numbers corresponding to those company customers (CustomerNumber).

While performing of order payment, the customer gets an offer to save the card for future payments using the One Click service. The proposal's text is located in the bottom of the screen:

If the customer refuses to save the card for future payments then all his payments actions remain as standard. By next payments, the customer will be asked again to save the card.

If the customer agrees to save the card, then to perform the next payment he will be prompted to enter only the CVC2 code, all other parameters of the card are automatically filled. Of course, for security reasons the card number is displayed on the screen using a mask.

If the customer uses several bank cards for payments on orders of the merchant, each card iconnects to the One Click service by the same rules. During the payment for the next order, the customer has the option to choose a card from the drop down list of its payment means, which reached a predetermined number of successful payments.

Customer is asked to confirm that he wants to pay through the One Click service before each next order payment:

If the customer agrees to use one of the previously saved cards to pay, then he is prompted to enter only the code CVC2 during the payment.
