If you shop or do business with a Square seller regularly, you’re able to store your payment card information for a seamless checkout experience.
Card on File Security
Square’s approach to security is designed to protect you with industry-leading standards for fraud protection. We keep your information safe and notify you anytime your saved payment card is charged so you can review your purchases, revoke authorization if you choose, and be on the lookout for unauthorized transactions. Learn more about Square’s security practices.
Card on File Email Notifications
When you first approve a merchant to save your card information, you will be required to provide your email address and your card’s billing ZIP code. Your email address will be used to notify you when your card is stored, if your email address is changed, when a payment is made using your stored payment card, and for marketing or other messages from this merchant.
Unlink or Delete Your Payment Card
To unlink your card from a Square seller, click the link at the bottom of one of your digital card on file receipts to reach your Card on File Dashboard. From your Dashboard, you can view or remove your payment cards linked to a Square seller.
