Delivery of information services to personal devices

摘要

A transaction processing system for sending user information data to a personal device, and an associated method are provided. The system comprises: a personal device, such as a balance display card; an interface device, such as a card reader for transmitting data to and from the card; a communications network connecting to the interface device; an issuer processor connected to the communications network; and a trusted network processor (TNP) processor connected to the communications network, interposed between the interface device and the issuer processor. The TNP processor is arranged to receive a transaction request message from a card user and to transmit a response message back to the personal device, the response message typically being a transaction authorization together with information for display on the card. The TNP processor is arranged to identify, dependent on properties of the transaction request message, whether the associated response message will require data to be sent to the user information device, and if so identified, to: route the transaction request message to the issuer processor using a standard message; receive the required data from the issuer processor using another standard message; match the received required data to the original request; generate an appropriate response message and script containing the required data; and transmit the response message back to the personal device thereby making the required information known to the user.

1. A transaction processing system for sending user information data to a personal device, the system comprising:
an integrated circuit card comprising: an integrated circuit element; and a display device for making information known to a user of the integrated circuit card; an interface device for transmitting data to and from the integrated circuit card; a communications network connecting to the interface device; an issuer processor connected to the communications network; and a trusted network processor (TNP) processor connected to the communications network, interposed between the interface device and the issuer processor, and arranged to receive, via an acquirer bank, a transaction request message from a user of the integrated circuit card and to transmit a response message back to the integrated circuit card; wherein the TNP processor is arranged to identify, dependent on properties of the transaction request message, whether the associated response message will require data related to an account balance or credit limit to be sent to the display device, the TNP processor further identifying that the transaction additionally calls for an authorization decision, and if so identified, to: split the transaction request message into a first standard message requesting authorization and a second standard message requesting the required user information; route the authorization request message to the issuer processor; route the required user information request message to the issuer processor; receive an authorization response message from the issuer using another standard message; receive the required data from the issuer processor using another standard message; match the received required data and authorization response to the original request; generate an appropriate response message and script containing the required data and authorization; and transmit the response message back to the integrated circuit card thereby making the required information known to the user and authorizing the transaction.
