NETBANX is the foremost service for processing internet based credit card payments in the UK. From our secure servers we have direct access into the UK banking gateways, which allows for instant authorisation of credit cards. Our system allows for the hosting of a secure form on our secure servers, or alternatively scripts to link into NETBANX payment gateway from your own secure server. When the order comes to NETBANX the credit card information is securely encrypted by the script and communicated via the Internet to one of NETBANX' gateway servers, which links immediately to the appropriate bank to request authorisation. All transactions that pass credit card number validity checks are sent to the bank for authorisation. At the same time, NETBANX' Fraud Control System runs a parallel check to investigate the likelihood of the transaction being fraudulent.

Security Digital Signatures
Digital signatures are used throughout the system in order to ensure that transactions arriving at a gateway are from an identifiable merchant, and that any information passed back to the merchant is from a NETBANX gateway. Each signature uniquely identifies its source. Gateways also communicate with each other and with the control system using such digital signatures. In the event that a merchant's digital signature becomes a security risk (e.g. if their server is stolen), the appropriate signature will be immediately revoked and will no longer function within the system.
