Embodiment

In order to more fully understand technology contents of the present invention, below in conjunction with specific embodiment technical scheme of the present invention is further introduced and explanation.

As shown in Figure 1, be the theory diagram of the preferred embodiment of the present invention, this preferred embodiment starts from step S1, at the input instruction of POS machine terminal and data message; Step S2: the backstage transaction program is resolved the instruction of POS machine terminal input, step S3: be obtained from definition information command or fixedly Transaction Information instruction, as for fixedly Transaction Information instruction, then enter the S4 step, as be the self-defined information instruction, then enter the S5 step; Step S4: the backstage transaction program is resolved the data message of input, obtains the Data Analysis reserve transaction processing of fixedly Transaction Information instruction and uses; Step S5: the backstage transaction program is to being obtained from the Data Analysis that defines information command and extracting label; Step S6: the data message after the backstage transaction program will be resolved according to the label that extracts writes in the TLV data structure of backstage, uses in order to transaction processing.

In the present embodiment, the label that extracts in step S5 is that POS machine backstage transaction program is according to instruction sequences and the corresponding label of instruction of the configuration of terminal menu flow process.

In the present embodiment, instruction and the data message of the input of POS machine terminal are two groups or more in step S1.

In the present embodiment, repeated execution of steps S2 to S6 writes in the TLV data structure of backstage according to label with the data that two groups or more are obtained from the definition information command, uses in order to transaction processing.

The below cancels as example explanation TLV data acquisition application in practice with Unionpay's benchmark service consumption.

Regulation according to " POS of China Unionpay terminal specification ", transaction is cancelled in magnetic stripe card consumption to be needed the operator after terminal is inputted former transaction voucher number, the former transaction magnetic card of brush, input password transaction to be sent to the backstage transaction program to process, and thin terminal platform issues as the menu primary data for the instruction flow of thin terminal platform this flow process is abstract.
