Yahoo! Wallet is a service that securely stores your credit card, billing, and shipping information so you don't ever have to type it in again. It makes shopping on Yahoo! safer, easier, and faster.

Express Checkout also allows you to easily save and retrieve your payment information for future purchases made from your computer. The next time you buy products or services from Yahoo! on your computer, your payment information will be pre-filled and ready to go. For security reasons, you will be required to log in using your Yahoo! ID and password each time you wish to access this payment information. In addition, this information will only be available from computers on which you have activated the Express Checkout feature.

With either of these services, your payment information will be stored securely and may be edited by you at any time by simply going to http://wallet.yahoo.com.
