Why Use A GPS Satellite When You Can Use 10,000 RFID Chips?
from the just-wondering dept
The well known Ginza shopping district of Tokyo is apparently about to get blanketed in approximately 10,000 RFID chips designed to help tourists and shoppers find their way around the neighborhood. The system requires a special handheld terminal to communicate with the RFIDs to tell you where you are, where you’re going and what’s around. However, overall this seems like a fairly inefficient method for doing location-based information. There are plenty of other tools out there, from GPS satellites to basic cellular triangulation. RFID chips certainly have some nice uses, but this one seems like a waste. While there certainly are limitations to GPS (especially around tall buildings), it still seems like this implementation doesn’t make that much sense. The fact that users need to get a special device to read things just seems pointless. You could accomplish the same sort of thing using cameraphone bar code scanners on an ordinary mobile phone, without forcing people to find this special reader device.
