Number Delimiter Validator
Created: 13 Nov 2012 | 2 comments
2 Questions:
1. Can anyone share any light on what "Number Delimiter" validators actually are? There is NO doco on them that I have found. They are used in the Medium and Narrow breadth Credit Card Number Data Identifier.
2. Regardless of Wide, Medium, or Narrow Credit Card Number data identifier... what are valid delimiters for Credit Card numbers? Just white space?
e.g. which of the following will trigger a match: (obviously if it would pass a LUHN check) Test it. You might be surprised.
1234-1234-1234-1234
#1234-1234-1234-1234#
