8 is a driving flowchart of the POS terminal 100 as a method of driving the POS system using the sequential fingerprint input of the present invention. Hereinafter, a method of driving the POS terminal 100 according to the present invention will be described with reference to the drawings.

When the POS system operation of the POS terminal 100 is started (S1000);

- The controller 110 of the POS terminal 100 performs step S1010 of setting the number i of the inputted fingerprints,

Next, the controller 110 of the POS terminal 100 displays the charging information for payment and receives the card information of the subscriber (step S1020).

Then, the controller 110 of the POS terminal 100 receives the fingerprint information from the subscriber (step S1030)

(S1040) of reconstructing the input fingerprint information with a series of codes and storing the read fingerprint image data in operation S1040.

Next, the controller 110 decrements the number i of input fingerprints by one (S1050);

- checking whether the decremented i is '0' in the above step, that is, whether the number i of inputted fingerprints is satisfied (S1060)

If it is determined in step S1060 that the number i of the input fingerprints is not satisfied, it is repeatedly performed in step S 1030 to receive fingerprint information from the subscriber if i is not 0,

If i is '0', the controller 110 reads the time stamp (S1070)

Next, the controller 110 performs step S1080 of transmitting the billing and card information for settlement, the multiple fingerprint image reading data, and the time stamp information to the payment server 200,

- The ear controller 110 receives the approval of payment from the payment server 200 (S1090)

- If the settlement is not approved from the payment server 200, a step of reporting a settlement error (S1095) is performed and the process is terminated (S1100)

- If payment is approved from the payment server 200, the process ends (S1100); and the POS system operation of the POS terminal 100 is terminated.

9 is a driving flowchart of the payment server 200 as a method of driving a POS system using the sequential fingerprint input of the present invention. Hereinafter, a method of driving the payment server 200 according to the present invention will be described with reference to the drawings.

- When the POS system operation of the payment server 200 is started (S2000);

- The payment server 200 receives payment request information including billing for payment, card information, multiple fingerprint image read data, and time stamp information from the POS terminal 100 (S2010)

Next, the control unit 210 of the payment server 200 performs step S2020 of extracting time stamp information from the received payment request information,

The control unit 210 of the payment server 200 compares the time stamp information transmitted from the POS terminal 100 with the time information provided from the real time clock 202 in the payment server 200, And determining whether the valid time stamp is valid (S2030).

The control unit 210 of the payment server 200 extracts billing and card information for payment transmitted from the POS terminal 100 (step S2030), if it is determined that the valid time stamp is valid S2040), < / RTI >

Next, the control unit 210 searches the subscriber DB 300 using the extracted card information and reads subscriber data (S2050).

The ear control unit 210 extracts a plurality of fingerprint image read data transmitted from the POS terminal 100 and reads i fingerprint data sets f1, f2, and ~ fi data from subscriber data retrieved from the subscriber DB 300 In step S2060,

(S2070) of comparing a plurality of fingerprint image read data transmitted from the POS terminal 100 with i fingerprint data sets f1, f2, ... fi read from the subscriber DB 300 and determining whether they match or not; .

If it is determined in step S2070 that the plurality of fingerprint image read data transmitted from the POS terminal 100 and the i pieces of fingerprint data sets f1, f2, and f3 read out from the subscriber DB 300 are compared, The control unit 210 performs the settlement using the billing and card information for settlement transmitted from the POS terminal 100 and transmits the approval result to the POS terminal 100 at step S2080, (Step S2100).

================================================== =============

The control unit 210 of the payment server 200 compares the time stamp information transmitted from the POS terminal 100 with the time information provided from the real time clock 202 in the payment server 200, The control unit 210 transmits the error information to the POS terminal 100 without performing settlement (S2090) when it is determined that the time stamp is invalid (S2030) The POS system operation of the server 200 is terminated (S2100).

================================================== =============

In step S2070 of comparing the plurality of fingerprint image read data transmitted from the POS terminal 100 and the i sets of fingerprint data sets f1, f2, ..., fi read out from the subscriber DB 300, The control unit 210 ends the POS system operation of the payment server 200 (S2100) by transmitting the error information to the POS terminal 100 (S2090) without performing settlement.

According to the POS system using the sequential fingerprint input of the present invention and the method of driving the same, the fingerprint information, the card information, and the time stamp, which sequentially receive two or more fingerprints and encode the recognition result, And the payment server decides the validity of the settlement time as a time stamp, inquires information provided in the subscriber DB, compares the fingerprint information with each other, and approves the settlement, and selects a fingerprint of a single user The payment is made by sequentially inputting the fingerprints of a plurality of users or by sequentially inputting the fingerprints of a plurality of users, whereby payment can be made by a single user or a joint user, and at the same time, security of payment information is provided.

Although the POS system using the sequential fingerprint input of the present invention and the driving method thereof have been described with reference to the limited embodiments and drawings, the present invention is not limited thereto and can be applied to a person having ordinary skill in the art It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims and their equivalents.
