That wouldn't work since CVV codes aren't sent with recurring transactions (they can't, since they cannot be stored).

Why can't they be stored?

Is it a legal requirement to prevent merchants without the CCV from using the credit card?

...oh wait

[duskwuff]

Because the CVV is used to indicate the "presence" of the customer at a transaction. CVV1 (which is on the magstripe) is used to indicate "card-present" physical transactions, CVV2 (printed on the back) is used for "customer just typed this in" non-physical transactions.

That makes much more sense. Thank you.

__should__ not be stored

Good point. Regardless, there should be __something__.
