This fall, San Francisco will implement the largest mesh network for monitoring parking to date. Around 6,000 wireless sensors from the San Francisco company Streetline will be fixed alongside as many parking spots, monitoring both parking availability and the volume and speed of passing traffic. The city hopes that displaying information from the sensors on Web maps, smart phones, and signs on the street will reduce the traffic and pollution caused by circling cars.
Of course if you have a networked parking meter system, one possibility is hacking:
They were able to replicate the signals sent and determine which was the one responsible for reporting the credit balance. The hackers then created a rogue card, which they modified to report a credit of $999.99. However, modifying a card to ignore the meter's requests and never alter its original balance is also possible.
