In a method of purchasing online, a client device of a customer (102) communicates a purchase selection which is received by a vendor computer system (104). The vendor computer system, in response, communicates a cost of the purchase selection and fund confirmation address to the client device. The client device (102) communicates a payment authorization for the cost that is received by a fund guardian (106). The client device also communicates biometric information. The fund guardian confirms the availability of sufficient funds to pay the cost. The biometric information is applied along with a stored biometric print to authenticate the customer. The vendor computer system communicates a fund confirmation address which is received by the fund guardian. When sufficient funds are available to pay the cost, and when the customer is authenticated, the fund guardian communicates a fund confirmation to the vendor computer system at the fund confirmation address. |
