    Status: Investigating We’re currently investigating an issue where some customers’ digital wallet tap payments (including Apple Pay, Google Pay, and Samsung Pay) are being declined at Square card readers. Affected buyers may see errors such as “This card is not accepted” or “Insert or use another card” when they try to tap to pay. As a workaround, please ask customers to use a physical card to tap, insert, or swipe at the point of sale.
