- Going to large event venues. Ticketmaster implemented a rotating barcode system, specifically to prevent people from using printed tickets. You have to either (1) use their webpage at the event where there's no cell service (2) install their malware on your phone or (3) on iOS add the ticket to Apple Wallet.
- Park in touristy areas. Parking meters still accept quarters, but a typical parking session is $20-$50, and the meters don't appear to be physically large enough to accept that many quarters.
- Charge your electric vehicle (Unless it's a tesla, maybe? Mine isn't.)
- Get into your office building (if you still have a commute)
- Get the lowest available rate for public transit
