Active Tags: RFID for LBS
Report here shows where RFID might be headed: active tags. Seems like with a wireless grid and active tags, geolocation without GPS should be possible – and at a much lower cost.
What’s this got to do with GIS programming ?
Coming up with an algorithm that updates cost based on congestion levels could be interesting. Assuming pricing is based on time of day, writing a path finding routine could also become more complex.
Seems like taxi services could change too, perhaps allowing trips to be purchased through an eBay-like auction. I guess the unions would not allow this though. That’s too bad, if taxis were cheaper perhaps more people would choose not to own a car.
