Spot on that’s what I did at tennis , sent my customer tickets by text , all worked fineU don't need internet on your phone. Just take a screenshot and save it to your photos on your phone and then just scan in like u would a paper ticket.
Even though the majority of people have smartphones, I agree that some don't and the AFL cannot be prejudice against those who don't have a phone, thus paper tickets should be allowed and are by what you stated.
