Fully Secure

Since PaymentSITE is hosted on Cardknox, sensitive payment data is kept away from your server—keeping you out of scope for PCI compliance. For added protection, PaymentSITE utilizes tokenization to encrypt card data and supports 3DS2 authentication technology to curb fraud and chargebacks.

Accept The Latest Digital Payments

Apple Pay
Google Pay

Streamline checkout with the convenience of Apple Pay and Google Pay. No more entering credit card numbers manually—customers can easily pay with the click of a button. Reduce friction and stay ahead of the payments curve by accepting the latest digital wallets.

Provide Additional Ways to Pay

Offer even more options to pay with QR codes and support for cryptocurrency payments. Customers can quickly scan and pay using a QR code on their invoice for a contactless checkout experience. You can also process popular cryptocurrencies without the fear of market volatility. Customers simply click the crypto button to pay with their crypto wallet, and Cardknox converts the currency to U.S. dollars.
