The lotto lottery ticket purchase / provision unit 620 of the lotto cashback provider / management agency 600 purchases the lottery lottery ticket by using the entire cashback points of the consumer according to the request, and then sends information related to the purchased lotto lottery ticket to the card inquiry machine. Provided (S410).

Subsequently, the unique number extraction unit 130 encrypts a number related to a credit card number and a transaction date and time authorization number among payment related information (such as merchant number and payment amount and card lookup number) of a product that a consumer wants to purchase. A predetermined number or more of unique numbers are extracted (S411).

The encryption algorithm described above is as follows.

The unique number extraction unit 130 applies the DES algorithm to the credit card number, transaction date and authorization number. First, DES is a data encryption standard standard established by the US Department of Commerce's Bureau of Standards based on IBM's proposal in 1997. As adopted by the Federal Government's Federal Information Processing Standard 46. This is a secret key method that uses a 64-bit key to encrypt 64-bit plain text by combining the former and the patient.

For example, the unique number extraction unit 130 is the sum of the last four digits of the credit card number and the four-digit reverse date (for example, 1230 if March 21) and the even number of the authorization number (for example, For example, if 47389562, 7 + 8 + 5 + 2 = 22) are extracted respectively.

Thereafter, the unique number extraction unit 130 sets the sum of all the extracted numbers as the first input value INPUT 1 and sets the KEY value that is specified in advance as the second input value INPUT 2 to determine the DES encryption algorithm. Apply. As a result, a certain number of unique numbers are extracted.

Thereafter, the card sales slip issuing unit 140 prints the bar code corresponding to the extracted unique number and the one-to-one correspondence with the lotto lottery ticket and the payment related information and provides it to the consumer (S412). And, the credit card company and merchant card sales slip is issued by printing only payment and lotto-related information to be separated from the consumer card sales slip.
