Radio-Frequency Identification (RFID) is an automatic identification method that uses radio signals, relying on storing and remotely retrieving data using RFID tags or transponders. RFID technology is becoming more and more popular and a central part of one's daily lives. Nowadays, one uses RFID tags for every kind of activities, such as: traveling by subway, entering/leaving a building/room, identifying the pets, location systems, inventories, etc. This technology is subject to all kinds of interference: electrical, reflections, attenuations, scattering, diffraction, among others. The electrical interference can come from electrical equipment nearby and usually causes problems with low-frequency RF equipment.
