A virtual payment system for paying for goods, services and content ordered over an internetwork is disclosed. The virtual payment system includes a commerce gateway. Buyers and sellers becomes registered participants by applying for virtual payment buyer and seller accounts. Once an account is established with the commerce gateway, a digital certificate is stored on the registered participant's computer. A buyer can then order a product, i.e., goods, services or content from a seller and charge it to the virtual payment account.

The buyer can settle the charges using a prepaid account, a credit account, or by using reward points earned through use of the virtual payment account. A buyer may create sub-accounts.
