Two quarters buy half an hour on a parking meter in downtown Stockton.
Now with a cell phone app called Parkmobile, Stockton drivers can scan special stickers on parking meters.
You can pay to park using the app and get a text alert on your cell phone when you meter is down to 15-minutes.
If you're stuck in a meeting blocks away, you can add more time on the meter with your phone.
Stockton Economic Development Director Micah Runner says it's good for drivers and it's good for business.
"I mean really what you're trying to do is help the overall customer experience and so the more you can attract people to feel comfortable coming downtown with m ore options to pay, the more successful the retailers can be."
Christyn Giannini parks in downtown Stockton, she likes the convenience.
"I think that's where we're headed with technology so it makes sense, everything has to be done by phone now."
You can still feed the meters with coins, but if you run out of time or money, a parking ticket is $43.
