To reverse (cancel) a Visa card payment tap on a GO Transit or UP Express fare payment device, press the “mode” button on the device screen. Continue pressing the button until you see “reverse fare," then tap the same Visa card or payment-enabled mobile or wearable device you tapped on. The device will display a green check symbol and a message, “Request for reversal recorded.” The reversal request is sent to the PRESTO back-end system for processing.
A reversal must be completed at the same GO station as your initial tap on within 45 minutes or the same UP Express station as your initial tap within 15 minutes.
