So I live down in Miami Beach and they just got this new program from eparksystems.com for parking meters. Basically you buy this little device which sits on your dash of your car and counts down time/money as opposed to putting the coins in the meters. It's great since you only pay for the time you need. To reload, you call the city and they give you a code which you input into the device which tells the device how much credit to issue onto the device. No communication with any mainframe is established. So there has got to be a way to hack this device to give you unlimited credits or at least a secret to the codes you have to enter. I haven't a clue, but though that others might have some insight.
