CardSave was created by an independent retailer back in 1995, when he grouped together with other small businesses to offer a lower-cost payments provider. Having become a member of the largest UK card processor (by transaction), WorldPay, the service has now grown to include 45,000 members. The Direct/Integrated method of integration allows the customers card details to be taken directly on the merchant’s website. This is the most flexible integration method technically, opening up the communication with the CardSave gateway. This integration method also lends itself to a high level experience for the customer as the payment section is integrated fully into the website. The look and feel of the payment page complies exactly to the website visual specification.
