I have a business requirement that forces me to store a customer\'s full credit card details (number, name, expiry date, CVV2) for a short period of time.
I don't believe it's actually illegal to store CVV info (in the sense that it's against any law), but it does violate Payment Card Industry rules, and they could impose any number of different sanctions. So, your requirements could actually result in you not being able to accept credit cards ;-(
