How would you use RFID's to improve your city?
Using RFIDs in taxis
May 08, 2013 Victoria D3

I would implement RFID technology in cabs in large cities such as New York. The current issue is that paying at the end of a cab ride can be a time-consuming process, especially if the rider is a visitor from a foreign country. Instead of fumbling with coins and taking valuable time out of both the driver and the rider's day, visitors and residents of the city could buy cab cards with RFIDs imbedded into them. At the beginning of the ride, the rider would merely show the driver his or her card. Then, at the end of the ride, the fare would automatically be subtracted from the card and the rider is billed later. The RFID would sense information from the cab's distance meter and instantly calculate the cost of the ride. This way, the rider can quickly and easily exit the car without any hassle. It is also safer than carrying around a credit card because it would only work in cabs - therefore there would be no risk for losing it and having purchases made elsewhere by a thief.
