The vendor (16) makes an agreement with a universal charge server (UCS) who assigns a unique A-number to each e-commerce client (ECC), who receives an order number for each purchase from an e-commerce operator (ECO) that also confirms the purchase to the UCS. The ECC then calls the UCS using the unique A-number in order to provide the order number, which is compared with that received from the ECO, and then the UCS or ECO contacts the vendor to confirm the purchase. The ECC is invoiced by the UCS. Payment transactions are therefore made without revealing the identity of the ECC over the internet. - An INDEPENDENT CLAIM is also included for the payment system. |
