If your screen brightness is too low, the barcode may have difficulty being scanned. Increase the brightness of your display to improve scanning. Copies of barcodes, screenshots or print outs will not be accepted.
If you add your tickets to your phone’s wallet, it may use near-field communication (NFC) technology instead of an on-screen barcode, eliminating the need to worry about your screen’s brightness—just hold your phone next to the usher’s scanner.
