As for numbers for a bingo game to be compared with a sequence (102) of numbers in each square of a bingo card (100) for a bingo game, which is randomly selected and issued before execution of a payment settlement process, a POS device extracts, as extracted numbers (204) for the bingo game, a combination of two adjacent numbers from number information included in purchased commodity information (202) printed on a receipt (200) during execution of the payment settlement process, registers, in an extracted number registration table, the extracted numbers in such a manner that the extracted numbers are linked to identification numbers respectively represented by a barcode (201) on the receipt (200) and a barcode (101) on the bingo card (100), and uses the extracted numbers (204) based on the purchased commodity information (202) to determine whether or not a bingo has occurred. When a bingo has occurred as a result of the bingo game, privileges, such as a free gift or issuance of a discount ticket, are handed to the customer. This contributes to an increase in the number of repeat customers and an increase in unit price per customer.
