Yes but not always applicable unfortunately… e.g. the other day I was in Italy, I needed to park on the publicly available parking which was paid to the municipality.
No other parking available anywhere near in 30 mins walking distance. (paid or free)
I had to download a 3rd party app that asked me to register. This app isn’t by the Italian government, it’s affiliated though.
So in that situation, I want nothing to do with your website or app, because I wouldn’t able to park.
Can you not pay with cash or card anywhere? What if you don't have a "smart" phone? I would categorically refuse to park anywhere that requires running a proprietary app on my device. Fortunately, in the States at least, I have not encountered such a place yet.
you can pay at the parking meters directly, no need for a 3rd party app
Have exactly the same situation with parking in Italy. Having a private company operating all paid parking on an island is not very healthy.
