May 2026: Service Disruption
Square experienced a service disruption lasting 1.9 hours where digital wallet tap payments were being declined at card readers, with customers seeing errors like "This card is not accepted" or "Insert or use another card." The issue was initially reported to affect Apple Pay, Google Pay, and Samsung Pay, but was later narrowed down to specifically impact Samsung Pay transactions. Customers were able to work around the issue by using physical cards to tap, insert, or swipe, or by using alternative digital wallets like Apple Pay or Google Pay.
