Card retention is a term that refers to the practice of keeping the card numbers of customers who use your service or website. The idea behind card retention is that if you can keep track of people who use your product, you can offer them special deals or promotions later on.

Card retention isn’t just for businesses that accept payment by credit card. It can also be used by companies that sell digital goods such as software, ebooks and music. In fact, some companies like Amazon have adopted this strategy for their entire business model.

With this strategy, you don’t need to send users through checkout again when they want to purchase something else on your site — they’ll already have all their information stored in your database. You can simply charge their card directly without asking them for any personal information again!
