# Random Bank Card Number Generator Online

TAG random

## Expression Syntax Description

1. \${numberRange@startNumber-endNumber@min@max} : numberRange is a fixed string, startNumber and endNumber are a number between 0 and 9, and endNumber needs to be greater than startNumber. min and max are integers greater than 1 but less than 1000, and max needs to be greater than or equal to min. Generate a random number string using numbers between startNumber and endNumber, with a string length between [min, max].
Example : \${numberRange@5-9@2@4} Generate a random string with a length range of [2,4] using the numbers 5, 6, 7, 8, and 9.
2. \${numberSelect@n1|n2|...@min@max} : numberSelect is a fixed string, n1, n2 is a number between 0 and 9. min and max are integers greater than 1 but less than 1000, and max needs to be greater than or equal to min. Generate a random number string using numbers such as n1 and n2, with a string length between [min, max].
Example : \${numberSelect@2|5|7@5@10} Use numbers 2, 5, and 7 to generate a random string with a length range of [5,10].
3. \${numberStep@start@step@paddingLength} : numberStep is a fixed string, start is the starting value, and can be any integer. step is the step size and can be any integer. paddingLength is an integer greater than 0, indicates the length of increasing or decreasing numbers that need to be aligned.
Example : \${numberStep@0@1@5} Generate a numeric string with a length of 5 ( 00000 , 00001 , 00002 , ... ). \${numberStep@1000@-5@4} Generate a numeric string with a length of 4 ( 1000 , 0995 , 0990 , ... ).
4. \${select@string1|string2|...} : select is a fixed string. Following is a list of candidate strings. Randomly select a string from the list of candidate strings.
Example : \${select@152|137} Randomly generate 152 or 137.
5. \${numberRandom@min@max@paddingLength}: Generate random numbers. numberRandom is a fixed string. min is the starting value, max is the maximum value, and paddingLength is an integer greater than 0, indicating the length of the number that needs to be aligned.
Example : \${numberRandom@0@9999999999999@13} random generate numbers in range [0,9999999999999), align to a length of 13 digits.

Random Bank Card Number Generator Online-instructions

Online random bank card number generation tool, using expression templates to randomly generate bank card numbers. This tool also supports generating numerical numbers such as serial numbers and phone numbers.

1. Expression : Enter an expression to generate the bank card number. Expressions support any normal characters and special keywords. Normal characters will be output as is, and expressions will be generated according to grammar rules. Please refer to the above expression syntax instructions for expression syntax.
2. Generate Count : The number of bank card numbers to generate, ranging from 1 to 1000000. Generate count exceeds 100, VIP membership is required. If you fill in a large number and require a unique bank card number, it may take a longer generation time.
3. Unique : Specify whether the generated bank card number needs to be unique. When determining whether it is unique, the content generated by the entire template is judged as a whole.
4. Join : How to concatenate multiple string results generated by templates. The join methods supported by this tool are as follows:
1. None : Directly concatenate the random strings generated by the template without using any connectors.
2. Comma : Use commas to concatenate randomly generated strings.
3. LF : Use new lines to connect randomly generated string data.
4. CRLF : Use carriage return and new line to connect randomly generated string data.
5. JSON : Convert the generated string array to JSON array format.
6. JSON Raw : Convert the generated string array to [str1,str2,str3] format.
7. JSON Compress : Convert the generated string array into JSON array format and compress it into its simplest form.
8. JSON Raw : Convert the generated string array to [str1,str2,str3] format and compress it into its simplest form.
