QuantumGateway: The Evolution of Payment Processing


We have developed our Transparent Database Engine for those merchants who collect and/or store all their customers' information. Most uses for this are automated billings.

By using this method the merchant can process the transaction from their website to us without their customer seeing it. The customer never leaves the merchant's website.

Any merchant using these methods should use a Secure Certificate to ensure the information is secure.

For this method the items that must be passed to the Transparent Database Engine are as follows.
