A wireless gadget from MobiPower might mean you’ll never have to carry change to feed a parking meter ever again:
The key is a small box that works similarly to the EZ Pass system. When a car enters certain parking zone, a light on the box will flash the parking rates for that area. One click, and the meter stars running. And the bill comes later in the mail. The best part? Drivers pay only for the exact number of minutes they park.
Of course, this system fails to take into account that many cities rely on the extra revenue they get from issuing parking tickets to people who forget to put enough money in a meter.
