should have put "reliably". either because not turned on, ticket not "active" on phone, not clear where to place, or machine not accepting who knows. where as QR is reliable, you can see its there.
nfc doesnt seem to work anyway, while the QR code does. so there's no reason for club to push away from printed QR codes, for those with printer. its rather exclusionary but thats the modern world, tech first access second.
