If you're asked for a PIN
Apple Cash doesn't require a PIN because every payment is authenticated by Face ID, Touch ID, or a secure passcode. There is also no card number, security code, or expiration date for your Apple Cash card.
If you're prompted by a terminal to enter a PIN to complete a debit transaction, enter a four-digit code, like 0000.
