Using myPOS Web Checkout your customers will be temporarily redirected to а secure hosted payment page. The payment gateway will handle and guide the customer during the payment process, will check the cardholder's sensitive data and will process a payment transaction through card schemes (VISA, MasterCard, American Express, JCB, UnionPay and Bancontact). If the customer's card is enrolled for 3D Secure, the customers will be redirected to their bank's website and after confirmation will be redirected back to your website. Another payment method is iDeal which is mainly for merchants in the Netherlands but it is available for everyone. The gateway will establish a connection with the client's bank and request to withdraw funds from the specified account.


Once the payment is complete, the customer will be returned to the merchant’s website. You will receive notification about the payment along with the transaction details.
