Hospital RFID Tags Interfere with Medical Devices: Study

This probably shouldn't come as any surprise to anyone who's experienced interference of one type or another from a wireless device of some kind. After all, we have all these signals filling the air around us. You would think someone would have tested this before.

It is not the RFID tag that causes the interference. These devices have no in-built power, and only respond a specific signal from a reader device. The article itself just about points this out, but that would make less of a sensational story. As long as the readers are used sensibly there is no problem at all. In fact where the tags are normally used, typically for laundry control or access control, there are no medical devices anywhere near the readers. Sometimes RFID is used for asset tracking, but it is highly unlikely someone will be checking an asset tag while someone is hooked up to or in the asset itself.
