[0048] Figure 1 Schematically shown is a flowchart of a method for bank card number segment management according to an embodiment of the present application. As Figure 1 shown, in the embodiment of the present application, a method for bank card number segment management is provided, which may include the following steps:

[0049] Step 202, determining the total set of bank card numbers.

[0050] According to the bank card specification recorded in the financial industry standard JR / T0052-2020 of the People's Republic of China, the bank card number is the number used to identify the issuing institution and the card, and is composed of the issuing institution identification code, the issuing institution self-defined bit, and the check bit.

[0051] It should be understood that for a continuous number range, usually the smallest number and the largest number in the range represent a certain number segment. For example, for 10 consecutive numbers 0001, 0002... 0010, the number segment can be represented as 0001~0010. For a bank card, the number segment of the card number can be calculated according to the value of the custom bit in the middle of the card number. Taking the card number with 19 digits, the first 6 digits are identification codes, the middle 12 digits are custom bits, and the last 1 digit is a check bit as an example. For 10 consecutive card numbers XXXXXX00000000001X, XXXXXX 00000000002 X... XXXXXX 00000000010 X, the number segment can be represented as XXXXXX 00000000001 X~XXXXXX 00000000010 X. By calculating the number segment of the card number, the card manufacturing institution can perform batch card manufacturing according to the number segment, and at the same time can generate a verification list according to the number segment, which is convenient for verifying the physical bank card after card manufacturing, for the warehousing handover of the bank card, and for the sorting of the warehoused bank cards.

[0052] In a specific implementation, the total set of card numbers can be determined in various ways. In one example, a card manufacturing task sheet can be obtained, and the total set of card numbers can be determined according to the card numbers to be manufactured on the card manufacturing task sheet.

[0053] Step 204, screen the total set of card numbers according to the first preset rule to obtain the starting card number set.

[0054] It should be noted that the values of the custom bits of different card numbers in the total set of card numbers may be continuous or discontinuous, that is, for the total set of card numbers, multiple number segments may need to be calculated. Therefore, it is necessary to determine the starting card number and the ending card number of each number segment. Figure 2 Schematically not shown Figure 1 in the schematic diagram of generating the number segment set. In Figure 2 the example shown, there are seven bank cards in the total set of card numbers M, and the values of the custom bits are 1, 2, 3, 5, 6, 8, and 12 respectively. According to the total set of card numbers M, there are a total of four number segments in the number segment set R, which are: the card number corresponding to 1 - the card number corresponding to 3, the card number corresponding to 5 - the card number corresponding to 6, the card number corresponding to 8 - the card number corresponding to 8, the card number corresponding to 12 - the card number corresponding to 12. The value of the custom bit of the starting card number of the first number segment is 1, and the value of the custom bit of the ending card number is 3; the value of the custom bit of the starting card number of the second number segment is 5, and the value of the custom bit of the ending card number is 3; the value of the custom bit of the starting card number of the third number segment is 8, and the value of the custom bit of the ending card number is 8; the value of the custom bit of the starting card number of the fourth number segment is 12, and the value of the custom bit of the ending card number is 12.

[0055] In the embodiments of the present application, the starting card number set is the set of starting card numbers of all number segments. In one example, the value of the custom bit of all card numbers in the total card number set can be decreased by 1 to obtain a first card number; it is determined whether the first card number exists in the total card number set; in the case where the first card number exists in the total card number set, the first card number is deleted from the total card number set to obtain the starting card number set.

[0056] Continue to refer to Figure 2 , for the total card number set M, if there exists a card number whose value of the custom bit is decreased by 1, the corresponding card number is deleted, and finally the starting card number set A is obtained.

[0057] Step 206, screen the total card number set according to the second preset rule to obtain the ending card number set.

[0058] In the embodiments of the present application, the ending card number set is the set of ending card numbers of all number segments. In one example, the value of the custom bit of all card numbers in the total card number set can be increased by 1 to obtain a second card number; it is determined whether the second card number exists in the total card number set; in the case where the second card number exists in the total card number set, the second card number is deleted from the total card number set to obtain the ending card number set.

[0059] Continue to refer to Figure 2 , for the total card number set M, if there exists a card number whose value of the custom bit is increased by 1, the corresponding card number is deleted, and finally the ending card number set B is obtained.

[0060] Step 208, calculate the number segments according to the starting card number set and the ending card number set to obtain the number segment set.

[0061] In a specific implementation process, the current bank card number can be read from the starting card number set; the third card number is found from the ending card number set according to the current bank card number; the current bank card number is used as the starting card number of the current number segment, the third card number is used as the ending card number of the current number segment, and the current number segment is generated according to the starting card number and the ending card number; return to the step of reading the current bank card number from the starting card number set until all the bank card numbers in the starting card number set are read to obtain all the number segments; determine all the number segments as the number segment set.

[0062] In one example, the value of the custom bit of the current bank card number can be obtained; a bank card number whose value of the custom bit is greater than or equal to the value of the custom bit of the current bank card number is found from the ending card number set to obtain a search result; the bank card number with the smallest value of the custom bit is determined from the search result; the bank card number with the smallest value of the custom bit is determined as the third card number.

[0063] Continue to refer to Figure 2, in the starting card number set A, for each bank card number a, find the smallest bank card number b (i.e., the third card number) in the ending card number set B whose custom bit value is greater than or equal to the custom bit value of the bank card number a. Combine the bank card number a and the bank card number b to form a number segment. Traverse all the bank card numbers in the starting card number set A to obtain all the number segments and form a number segment set.

[0064] In an example, the generation process of the number segment set can be implemented through Structured Query Language (SQL) statements. For example, use the SELECT statement to find the card numbers with the custom bit value decreased by 1 in the total card number set, delete the corresponding card numbers, and obtain the starting card number set A; then use the SELECT statement to find the card numbers with the custom bit value increased by 1 in the total card number set, delete the corresponding card numbers, and obtain the ending card number set B; find the smallest bank card number b in the ending card number set B whose custom bit value is greater than or equal to the custom bit value of the bank card number a in the starting card number set A; combine the bank card number a and the bank card number b to generate a number segment.

[0065] In the embodiment of the present application, by determining the total card number set of bank cards; screening the total card number set according to the first preset rule to obtain the starting card number set; screening the card number set according to the second preset rule to obtain the ending card number set; calculating the number segments based on the starting card number set and the ending card number set to obtain the number segment set. The calculation of the number segments is realized through the screening of the card numbers, which improves the calculation efficiency of the number segment set, provides a basis for the bank's batch card production and the verification work of bank cards, avoids errors in operations such as card production, sorting, handover, and warehousing, and improves the card production efficiency.

[0066] Figure 3 Schematically shows a flowchart of a method for bank card number segment management according to an embodiment of the present application. As Figure 3 shown, in the embodiment of the present application, a method for bank card number segment management is provided, which may further include the following steps:

[0067] Step 210, determine the number of bank card numbers in each number segment in the number segment set.

[0068] Step 212, generate a verification list according to the number segment and the number of bank card numbers corresponding to the number segment.

[0069] Among them, the verification list can be a card production list for verifying the physical quantity of bank cards after card production, or a handover list for the physical warehousing of bank cards, or a sorting list for sorting the warehoused bank cards. The embodiment of the present application does not limit this.

[0070] In one example, the bank name, branch name, and branch number can be obtained, and a card production list can be generated based on the bank name, branch name, branch number, number segment, and the quantity of bank cards corresponding to each number segment. After card production is completed, the quantity verification of bank cards can be completed according to the number segments and quantities of bank cards applied for by each branch in the card production list.

[0071] In another example, information such as the name of the bank card, card type, product number, recipient, and giver can be obtained, and a handover list can be generated based on this information, the starting card number, ending card number, and quantity in the number segment. When the bank cards are warehoused, the bank cards are verified and warehoused according to the handover list.

[0072] In another example, the bank name, branch name, and branch number can be obtained, and a sorting list can be generated based on the bank name, branch name, branch number, number segment, and quantity. After the bank cards are warehoused, the bank cards are sorted according to the sorting list.

[0073] In the embodiments of the present application, by generating a verification list according to the number segment set, business personnel can verify bank cards according to the verification list, reducing the probability of errors in links such as card production, sorting, handover, and warehousing, and improving the work experience of business personnel.
