Is RFID harmful?

RFID is a wireless technology that relies on a network of fixed and mobile readers and tags, relaying information with radio frequency (RF) signals. While the larger-scale deployment of RFID is relatively new, the use of other radio frequency based wireless technologies is already widespread: television, FM radio, mobile phones…  While there has been concern about the possible negative health impact of RF, a large number of studies about exposure to radio frequency have been carried out over the past few . To date the results of these studies provide no consistent or convincing evidence of a causal relationship between radio frequency exposure (within safety limits) and any adverse effect on health.  Scientists and regulators, however, are continuing with their research programmes and continually re-examining their findings.

Radio frequency exposure is regulated; safety limits are set in both national and international regulations for operating radio frequency equipment  in the workplace environment and in public and residential environments.
