San Francisco is replacing 5,000 of it's parking meters with new Smart Parking Meters. Not only will the meters take credit cards, they also have sensors in the pavement that can locate clear spots, and (in the near future) tell your smartphone where the nearest parking space can be found (yes, soon there will be an Ap for that). Another smartphone feature is a phone alert when your parking time gets low, and the possibility of paying for the first and a subsequent time block by phone.
