The District’s new Parkmobile app, which allows you to use your smart phone to pay for parking, is awesome. Except for when it doesn’t stop you from getting a parking ticket.

The Examiner reports that despite it’s increasing use, drivers who have used Parkmobile to pay for parking have still gotten tickets — to the tune of some 25 mistaken tickets a day. Writes the Examiner:

The system, implemented citywide in July, is supposed to update parking enforcement officers’ hand-held devices as soon as a phone payment is made. But sometimes that data doesn’t load immediately, DDOT spokesman John Lisle said, leading the officer to believe the driver didn’t pay.

“There are times there is a delay,” Lisle said, adding that the city is updating the pay-by-phone software to fix the glitches. “We’re working to eliminate those problems, and if it does happen to somebody, they can [appeal] it to the Department of Motor Vehicles.”

Moreover, say city officials, you’re still very unlikely to get a ticket if you use the system — it’s used some 10,000 times each day, after all.
