both of these are 100% fine. The business operated and was successful. Perfect is the enemy of good. Prematurely optimizing especially in tech is one way to guarantee your business fails. You should always use what is cheap and works for as long as possible and then address the issue when the time is right.

Let's roll back the clock to when this was really popular. The issue was recurring billing. The only way to charge the card was to keep the CVV. We had to wait for the credit card companies to solve this problem for us. At least as far as I'm aware, when the CVV was invented they didn't provide any mechanism to keep billing the same card without keeping the CVV on file.
