Digital solutions don't have to be abusive.
Where I live the city commissioned its own mobile app for parking, and all numbered parking spots in the city use that app.
There are private lots that use Honk or Robbins or whatever, but the municipal lots and all parallel parking spaces downtown all use the same single app and the revenue goes to the city.
The city parking app works reasonably well, no ads, it just does one thing. If you leave early you open the app and hit "stop parking" and it only charges you the 37 cents or whatever that you actually consumed. It sends you a push notification when your parking is about to expire. And if you don't like the app for whatever reason, you can still pay with a card at the pay machines on every block. It's unglamorous, but it's fantastic technology.
