If you have to ask, you don't want to do it.

There is another solution that allows for essentially identical
business logic - store the card number with your gateway.

Authorize.net provides Customer Information Manager.  Quantum Gateway
provides "quantum vault".  Last time I looked paypal/google checkout
didn't have this, they may now.  Amazon payments may have something
like this.  There are also a number of startups whose names escape me
at the moment who purport to solve payments.

Basics of how it works:
You and your customer have a secure session.
You get and send your customers's card number to the gateway (again
over a secure session)
The gateway provides you a unique identifier.
In the future, when you want to charge that customer's card you send
the gateway the unique identifier instead of the full card.

If you want to chat more about specifics, send me an email offline.
