Credit Card Data

Matches valid credit card numbers (i.e with valid Luhn checksum) in all varieties: lengths (depending on the credit card scheme), formattings (continuous, space-delimited), encodings (when submitted in the URL).

Example

1378282246310005
23782 822463 10005
338520000023236
44917%206100%200000%200000%20003

Pattern:

1CREDITCARD:cc EOL;

Parsing results creditcard numbers in lines 1,2 and 4 parsed into long field cc. Parsing fails for line 3 due to invalid Luhn check digit.
