Transaction processing system and method

Abstract

In an embodiment, a transaction processing system includes a first wireless terminal in which payment information associated with a customer is stored and a shopping cart with a code reader and a second wireless terminal. The second wireless terminal is configured to transmit a commodity code read by the code reader to a server system to generate, on the server system, a shopping list including the commodity code. The second wireless terminal receives, from the server system, payment amount data indicating a total payment amount due for purchase of commodities on the shopping list and then transmits a settlement instruction along with the payment amount data to the first wireless terminal so the first wireless terminal can perform a settlement operation with a settlement server using the payment information stored in the first wireless terminal.
