Apple Cash may soon offer a ""virtual card number"" in the iOS 17.4 beta that can be used to shop online where Apple Pay isn't available. The new feature promises a new security code for every transaction, and the number can be accessed in Safari's Autofill for easy use. In the beta, Apple Cash users are prompted to ""set up a virtual card number."" Once that's done, you can see it via the settings menu, including the card number, expiration date, and security code. The number is separate from the one used for Apple Pay transactions and can be changed. As a reminder, Apple Cash is similar to a debit card, allowing you to send and receive money via Apple Pay and the Message app. Funds can be stored, and they can be linked to a bank account or other debit card to transfer money back and forth. Apple Pay cashback earnings are paid off as Apple Cash, and funds can be used to pay off Apple Pay balances.
