Abstract

The utility model discloses a wireless POS communication connecting system which comprises a wireless POS machine, a NAC machine, a front machine and a business main machine; the wireless POS machine is provided with a GSM module which is connected with the phone network of the NAC machine through the GSM network; the NAC machine, the front machine and the business main machine are connected through the data wire. The utility model needs not to distribute phone wire for each POS machine; the utility model can realize mobile bank transaction in a short period of time; the utility model protects the prior investment of the bank or the gold card center; and compared with the SMS art, the utility model is steady and reliable, and the utility model can finish transaction of the bank through the position of the GSM mobile phone.

Description

The wireless POS communication connecting system

Technical field

The utility model belongs to wireless communication field, relates in particular to the wireless POS machine communications field.

Background technology

Point of sales terminal point of sale (hereinafter to be referred as the POS machine), be to accept magnetic stripe card information, has communication function, and accept teller's instruction and finish the financial transaction information and the equipment of exchange for information about, can be divided into two kinds of wired POS machine and wireless POS machines according to the difference of its communication modes.

The most of networking mode that adopts wired POS machine in early stage bank or gold card center, as shown in Figure 1, it mainly comprises POS machine 1, NAC machine 2 (Network Access Controller, be network controller), front end processor 3 and professional main frame 4 form, link to each other by fixed-line telephone network 5 between POS machine 1 and the NAC machine 2, NAC machine 2, front end processor 3 link to each other by data wire 6 with professional main frame 4.This wired POS communication connecting system links to each other by the equipment such as NAC machine 2 of fixed-line telephone network with bank or gold card center one end by built-in wired MODEM in POS machine 1, finishes financial transaction service.It has satisfied at present the business of POS machines such as market on the fixing sales counter, finance substantially, but owing to be required to be telephone wire of every POS machine 1 cloth, POS machine 1 can't move simultaneously, must finish financial transaction in the fixed location, makes troubles for it is widely-used.

Some producers or bank adopt the wireless POS communication connecting system at present, as shown in Figure 2, it mainly comprises wireless POS machine 7, sms center 8, proprietary MODEM9, front end processor 3 and professional main frame 4, pass through GSM network 10 (GlobalSystem for Mobile communications between wireless POS machine 7 and the sms center 8, be gsm) link to each other, sms center 8 is set up dedicated gateway, sms center 8 is by linking to each other special-purpose MODEM9 and front end processor 3 by dedicated data line 11 (X.25 or DDN) between dedicated gateway and the special-purpose MODEM9, link to each other by data wire 6 between the professional main frame 4.This wireless POS communication connecting system is by the wireless POS machine 7 of built-in gsm module, utilize short message (SMS) technology of GSM network, dedicated gateway by sms center 8 receives and sends the data of financial transaction bag, and link to each other with professional main frame 4 with the front end processor 3 at bank or gold card center by dedicated data line 11, finish financial transaction.Because the wireless POS communication connecting system of commonly using adopts the data format of SMS technology different with the data format of original financial transaction, must set up dedicated gateway to go conversion, by dedicated data line 11, special-purpose MODEM9, be connected to and front end processor 3, also need develop the application software on front end processor software and the wireless POS machine 7 simultaneously again, can't utilize the original investment at bank or gold card center preferably, by analysis, there is following deficiency:

1, must drop into very big human and material resources, financial resources again, resource is developed again, and cost is higher;

2, the reliability of new network configuration and new software, that stability also needs the time to go is perfect;

3, the SMS technology of GSM network is the technology at the signaling channel transmitting data of GSM, can only transmit 140 characters (when adopting 8 bit data positions) at most at every turn, passage because of the signaling exchange during just as gsm communication at the beginning of the design of the signaling channel of GSM network, and be subjected to the restriction of Speech Communication load, be that Speech Communication is many more, the bandwidth of occupied signaling channel is just many more, can be just few more for the bandwidth of SMS, so SMS is used for transmitting the data instability, sometimes very fast, sometimes have delay for a long time, cause the wait of financial transaction or lose.

Summary of the invention

The utility model mainly solves the difficult problem that located by prior art can't be utilized the original investment at bank or gold card center preferably, and all wireless POS communication connecting systems preferably of a kind of reliability and stability are provided.

For solving above-mentioned technical barrier, the utility model mainly comprises wireless POS machine, NAC machine, front end processor and professional main frame, built-in gsm module in the wireless POS machine, wireless POS machine links to each other with the fixed-line telephone network that is deployed to the NAC machine by the GSM network, links to each other by data wire between NAC machine, front end processor, professional main frame.

Compare with wired POS communication connecting system of commonly using, the utility model need not to lay telephone wire into every POS machine, realizes mobile financial transaction, has expanded the application scenario of POS machine, as Electronic Finance means of payment such as charge to the doorstep, ecommerce dispensings.

Compare with the wireless POS communication connecting system of commonly using, the utlity model has following advantage:

1, protected the original investment at bank or gold card center, original NAC machine, front end processor, professional main frame need not change, and front end processor software need not change simultaneously, and the application software on the POS machine is only done the modification of a small amount of communication mode and can be used;

2, can at short notice reliably, stably realize portable bank transaction;

3, compare with the SMS technology, stable, reliable, as long as can just can finish bank transaction by the place of GSM mobile handset conversation.

Fig. 4 is the structural representation of another embodiment of the utility model.

Execution mode

See also shown in Figure 3, the utility model mainly comprises wireless POS machine 7, NAC machine 2, front end processor 3 and professional main frame 4, built-in gsm module in the wireless POS machine 7, wireless POS machine 7 links to each other with the fixed-line telephone network 5 that is deployed to NAC machine 2 by

GSM network

10, and 4 in NAC machine 2, front end processor 3, professional main frame link to each other by data wire.This kind structure adopts itself and the internetwork data service function of GSM by the wireless modem of built-in gsm module in wireless POS machine 7, passes through GSM network 10 and links to each other with the equipment of fixed-line telephone network 5 with bank or gold card center, finishes financial transaction.

For accomplishing generalization, in the wireless POS machine 7 of the present utility model, its CPU can link to each other with gsm module by the standard interface of RS232C.In addition at the utility model structure for being applicable to the bank finance communication system, the data transmission format between its wireless POS machine and NAC machine is ISO8583.

Because the GSM network 10 of different operators exists difference, same operator also has difference at the GSM of zones of different network 10, as shown in Figure 4, can before NAC machine 2, set up MODEM, fixation phone line 5 is connected to MODEM11, MODEM11 is connected to NAC machine 2 by data wire 6, arrives NAC machine 2 by the MODEM11 translation data, promptly applicable to any gsm system.
