Smart Card? A Study of ElectroMagnetic Fields Produced by RFID Transmitters
2011 VIRTUAL SCIENCE FAIR ENTRY
Radio Frequency Identification (RFID) is a ubiquitous form of Near Field Communication (NFC) technology that has been adapted by numerous industries to identify items, goods, and people. RFID systems operate through a transmitter, which constantly releases pulses of ElectroMagnetic energy. When a card is placed within range of the transmitter, the energy found in the ElectroMagnetic Field (EMF) powers the card, enabling the card to execute the requested command and send the result back to the transmitter. As RFID technology is becoming more integrated into our daily lives (office buildings, shipment tracking, theft prevention, passports, credit cards, transportation systems, etc.), it is even more important to understand the possible health risks from the EMF emitted by RFID transponders. This experiment tested the EMF to determine the overall safety of these devices. A TriField 100XE meter was placed adjacent to the transmitter to record the strength of the field before, during, and after RFID cards were scanned by various transmitters. At the conclusion of the experiment, 16 different transponders were tested in 6 different systems, and a total of 80 samples were collected.
