What type of technology would you recommend I use?
I would say your best option would be to utilize a GPS tracking device. RFID is a relatively short-range technology, and usually isn't very suitable for tracking individuals, unless you wanted to monitor then within a facility. For example, you could implement Wi-Fi-based active RFID technology to track patients within a hospital or a chemical plant.
