Abstract

A system comprises a wireless interface coupled to a transaction manager. The wireless interface receives user information, including a user speech sample and a user account code, from a wireless communication device over a wireless communication link. The transaction manager transfers the user speech sample and the user account code to a validation system. The transaction manager receives and displays validation information from the validation system. The validation information indicates if the user is authentic and if the account code is valid. The validation information may include a picture of the user that is displayed by the transaction manager.

Claims

1. A wireless telephone to handle a transaction to purchase a product, the wireless telephone comprising:

a memory configured to store a plurality of account codes and account balances for the account codes;

a display configured to display a first user prompt for a voice-authenticated transaction, to display a second user prompt to select one of the account codes, and to display a third user prompt for a user speech sample to voice-authenticate the transaction;

a microphone configured to receive the user speech sample to voice-authenticate the transaction;

keys configured to receive a first user selection of the voice-authenticated transaction and a second user selection of a selected one of the account codes;

a wireless interface configured to transfer for the transaction the user speech sample and the selected one of the account codes, and to receive for the transaction a transaction code, a product identification, and a purchase price;

control circuitry configured to direct the display to display the first user prompt, and responsive to the first user selection from the keys, to direct the display to display the second user prompt, and responsive to the second user selection from the keys, to direct the display to display the third user prompt, to direct the wireless interface to transfer the speech sample and the selected one of the account codes, to direct the memory to store for the transaction the transaction code, the product identification, the purchase price, a date for the transaction, and an account balance after the transaction for the selected one of the account codes; and

wherein the wireless telephone is configured to communicate over a public wireless communication network.
