It’s kinda easy to justify though from a financial standpoint. If the parking meters take cash, you need all the hardware to accept and secure the cash. Then you need somebody to go around at some point and actually physically collect the cash. Then someone has to reconcile the cash, etc.

So at least from that angle I see it as an easy “government is actually trying to be more efficient” argument.

As a user cash is a pain in the ass. I have to count it out, keep it in my pockets, etc. So much easier to just tap my phone or my card. But yeah that’s a tradeoff in the classic “You’re trading X for convenience”.
