CyberCash

One of the key components of an e-commerce web site is credit card processing capabilities. One such credit card processing service, that is supported by PHP, is CashRegister, from CyberCash. The CashRegister service enables merchants to make financial transactions over the Internet in real-time. CashRegister works by first you (the merchant) receiving an order request from a customer and sending an authorization request to the CashRegister server. Next the CashRegister server returns either an approved or declined message back to you. If the authorization is approved the order request is completed and the customer receives their goods or services. Communications are encrypted using SSL and Triple DES at the various stages in the process.
