Your buyer signs up on your website and makes the first purchase.
The card details that he/she enters (card number, first and last name of the cardholder, CVV2/CVC2, expiry date) for the initial transaction are tokenized by the PayOp system.
The reference ID of the first payment is stored on the system.
Next time the customer buys in your online store and clicks on the Pay with card button, the system uses the reference ID of the initial transaction and charges his/her card. If the customer was not authorised in the PayOp he had to do so.
And that’s all! With only one click, your buyer makes a payment and brings you profit.
