Shop settlement method, system and program
First Claim
1. A shop settlement method using a cell phone, having a camera and an IC chip, and a POS register terminal, the method comprising:
- generating, at said POS register terminal, settlement request information including an amount of settlement upon receipt of an operational input of IC card settlement to said POS register terminal;
generating a request barcode from said settlement request information and causing screen display or printing output by said POS register terminal;
restoring said settlement request information by imaging said request barcode by the camera of said cell phone;
subtracting an amount of settlement of the settlement request information restored from a value charged to the IC chip of said cell phone;
generating settlement response information including a balance after settlement of said IC chip;
causing screen display by said cell phone by generating a response barcode from said settlement response information;
restoring said settlement response information by reading out said response barcode of said POS register terminal; and
confirming the end of IC card settlement from the restored settlement response information, thereby printing a receipt by said POS register terminal.

Abstract
In a shop POS register terminal, a settlement request-generating unit generates settlement request information, which includes an amount of settlement. A request barcode is generated from the settlement request information, and the POS register terminal displays or prints the information. In a cell phone, the camera restores the settlement request information through the request barcode image. The amount of settlement is subtracted from a value charged to an IC chip. Settlement response information is generated, which includes the balance after settlement of the IC chip. Then a response barcode is generated from the settlement response information, and causes the cell phone to display the same. In the POS register terminal, the response barcode is read out to restore the settlement response information. Then an IC card settlement-ending unit confirms and causes the POS register terminal to print the receipt.
