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#

Answer to #2:

The only valid delimiters for the Credit Card Number Data Identifer (Wide, Medium, or Narrow breadth) are:

PRECEDING Characters must be:

Any White Space or one of the following characters:

#  (  )  =  ;  :  '  " , >

POST Characters must be:

Any White Space or one of the following characters:

,  .  "  '  (  )  <  ;

 

INVALID Pre and Post characters to a CC# are:

\S\w

Validators are validation checks applied to data matched by a data identifier
pattern. Validators help refine the scope of detection and reduce false positives.
Many validators allow for data input. For example, the Keyword validator lets you
enter a list of keywords.
 
Number Delimiter Validates a match by checking the surrounding digits.
