Pedestrians cross 42nd street in New York on Wednesday, September 17, 2014 past a billboard advertising a Zara clothing store that is currently under renovation. Zara announced that it will start using RFID chips in its merchandise to keep better control over its inventory. Zara has 2000 stores worldwide and half of them will be using the technology by the end of 2014. (© Richard B. Levine)
