[Analysis & Solutions]

Hi Folks:

I'm happy to announce the latest versions of my
Credit Card Validation Solution.  This includes a new JSP Edition and
reworking the PHP and Perl Editions into an Object Oriented paradigm. 

If you're using a version prior to the following, please upgrade:
  Ed.   Ver  URI
  ----  ---  ---
  JSP   4.2  http://www.analysisandsolutions.com/code/ccvs-jsp.htm 
  Perl  4.7  http://www.analysisandsolutions.com/code/ccvs-pl.htm
  PHP   4.4  http://www.analysisandsolutions.com/code/ccvs-ph.htm

An older version of it is also available for Visual Basic at
http://www.analysisandsolutions.com/code/ccvs-vb.htm

If you're not familliar with these scripts, here's a quick description:

It ensures credit card numbers are keyed in correctly. Includes checks
that the length is correct, the first four digits are within accepted
ranges, the number passes the Mod 10 Checksum and that you accept the
given type of card. Just to be clear, this process does not check with
banks or credit card companies to see if the card number given is actually
associated with a good account. It just checks to see if the number
matches the expected format.

Enjoy,

--Dan
