A person is attempting to pay for a purchase at a self-checkout in a supermarket. The phone screen displays a Dutch language message: “Om veiligheidsredenen moet u bewijzen dat u het bent voordat u contactloos betaalt. Laat verifieren dat u het bent.” They hold the phone over the payment terminal twice, but the phone does not appear to process the transaction. They swipe the screen, and attempt to tap again.
