A “cash app card number” is a virtual credit card number associated with your Cash App account. You can use this virtual number to make online or in-store purchases, and the funds will be deducted from your Cash App balance.
Cash app card numbers are a convenient and secure way to make payments. They are especially useful if you don’t want to share your real credit card number with a merchant. Also, they can help you avoid overspending by setting spending limits.
