(Inspired by a post by spikesgirl58.)
In San Francisco, coin meters gave way to card-operated ones a few years back. Here in Portland, it's mostly kiosks (some solar-powered) where you insert either cash or a card and get a ticket, or else "pay-by-plate" and enter your license plate number on an alphanumeric keypad. (The latter kind are ticketless.)
A few weeks ago I took a drive to Hood River, about an hour away, and discovered coin-operated meters still in service there. I had to duck into a coffee shop to get change because I'd stopped carrying around quarters!
