The other problem, in the US at least, is that cash is very low value (inflation), and dollar coins never caught on. I'm not trying to carry around $6 in quarters to park for 2 hours. And that's a pretty inexpensive parking spot.

...are you implying that digital money is worth more than digital?

because I doubt anyone who spends cash regularly is holding much of it long enough to lose value to the digital ones in their checking account.

		No, they're implying that you need a lot of coins to pay for parking. If you need $6 to pay for parking, and the largest commonly available coin is a quarter, that means you need 24 coins to pay. If the value of currency was such that the parking only costed $3, or if dollar coins were more common, you'd need less coins to pay.
