RFID Journal Staff asked 3 years ago I am developing a solution utilizing active 2.4 GHz readers and tags to track students and personnel in an indoor environment. Would this technology be safe around kids?

Olamide,
It would not be possible to give you a definitive answer since no studies on this subject have been conducted. It would depend on the intensity of the RF signal and the frequency at which the transponders beacon. I believe the transponders are safe, especially if they beacon only every 30 seconds or so, because the signal is not as strong as a cell phone signal and would not last as long—but, again, no studies have been carried out to certify that there are no negative health effects from active transponders operating at 2.45 GHz.
