Square Cash supports standard, U.S.-issued AMEX, Visa, MasterCard, and Discover credit and debit cards. We don’t currently support ATM, PayPal, or prepaid bank cards.
Once you’ve linked a debit card to the app, you’ll have the option to link a credit card as well. If you have a credit and debit card linked, you’ll be prompted to select a card each time you send cash.
It’s important to note that payments sent from a credit card incur a 3% fee which is added to the payment total (i.e. if you send $50.00 from a credit card, you’ll see a $51.50 charge to your card).
To link your card, you’ll need to provide:
- The full card number
- Expiration date
- CVV (3-digit number located on the back of the card, or 4-digit number on the front if it’s AMEX)
- Billing ZIP code
