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:
The positive response on the proposal is selected by default!
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.
