In my area ("the DMV"

a major parking management company switched to requiring the exclsive use of their phone app to pay. Shoppers apparently were not the only folks to refuse to download their app. They have just returned to whatever each location was doing pre-covid, i.e., either cc or cash. And, we still catch attendants accepting cash at c"cc only" locations.
