Paper for me. I don't mind ordering print out tickets online, cause I still get a paper copy. But NEVER a cellphone scan ticket. Matter-of-fact, I refuse to conduct ANY kind of transaction via phone. They just don't have the same robust anti-malware and hacking resistance as my computer. I once watched my supposedly protected phone activate and performing commands while I was holding it in my hand. Including sending out emergency calls to family members. Who of course anxiously contacted me about my location and what kind of help I needed. Of course calls claiming I owed money and what to do to pay and other spoof, spam, and scam, stuff. All this despite supposedly top of the line protection $ervice. So I made up my mind to NEVER, EVER conduct financial activity connected to my phone outside of credit card paying my phone service. And that card gets deactivated if it even smells like it is being hacked. So paper for me, and yes, I know, nothing is foolproof or 100% safe these days, but I can at least minimize my exposure. So I never phone scan anything, I never conduct a transaction despite pressure from friends, my bank, and some businesses to do so because it's faster and easier. Paper, paper, paper, for me. And the day they say, "You can't do that anymore," I'll do walk-ins with cash. Or move to Tibet, the Andes, or some other isolated non-digitalized region if I have to.
