<p>A point of sale system comprising at least one point-of-sale terminal for transmitting transaction request in response to a user input; and a gateway server (TGS) for receiving said transaction requests and reformatting the request in conformance with a host financial transaction processing computer connected to the gateway server, such that data traffic between the terminal and the TGS is reduced. In an alternate embodiment, the invention provides a method for communicating information between a terminal and a host in a wireless point of sale system, the method comprising the steps of sending a transaction request to a transaction gateway server; establishing a session between the transaction gateway server and a financial processing host computer; reframing the transaction request at the gateway server for transmission to the financial processing host; sending the reframed request to the host; receiving at the server a response from said host; and generating at said server a terminal response from said host response, whereby the host and terminal do not communicate directly. In a further embodiment of the invention there is provided a method for handling exeption conditions in a transaction between a terminal and a transaction processing host.</p> |
