Do the RFID tags interfere with hospital instruments with electromagnetic interference EMI?

Passive RFID tags do not emit any signal until activated by a reader, so emissions are quite low compared to active RFID for real time locating systems. However, a study conducted in a non-clinical setting by the University of Amsterdam and published in the Journal of the American Medical found that passive RFID technology did generate some interference with medical devices when the RFID equipment was placed very close by. A follow-up study conducted by researchers from Indiana University, Purdue University and RFID vendor BlueBean found no such interference in tests conducted in an actual clinical setting. While the risk is quite low, hospitals should conduct a thorough EMI assessment to avoid any potential interference.
