- This module does not tell you whether the number is on an
- actual card, only whether it might conceivably be on a
- real card. To verify whether a card is real, or whether
- it's been stolen, or what its balance is, you need a
- Merchant ID, which gives you access to credit card
- databases. The Perl Journal
- (http://work.media.mit.edu/tpj) has a Merchant ID so that
- I can accept MasterCard and VISA payments; it comes with
- the little pushbutton/slide-your-card-through device
- you've seen in restaurants and stores. That device
- calculates the checksum for you, so I don't actually use
- this module.

- These subroutines will also work if you provide the
- arguments as numbers instead of strings, e.g.
- validate(5276440065421319).
