RFID Question & Answers July 12, 2021 By WatElectronics This article lists 100 RFID MCQs for engineering students. All the RFID Technology Questions & Answers given below includes solution and link wherever possible to the relevant topic. The radio frequency identification reader consists of a radio frequency module, a control unit, and an antenna coil that generates a high-frequency electromagnetic field on the other hand the tag is usually a passive component that consists of an antenna and an electronic microchip. The RFID doesn’t require a direct line of sight & the RFID tags can be reused and rewritten. The RFID reader, antenna, RFID tags, cables are the basic components of the RFID system. For high frequency and low-frequency RFID tags, the working principle is based on inductive coupling and for ultrahigh-frequency RFID tags, the working principle is based on electromagnetic coupling. The RFID systems consist of two components mainly RFID readers and RFID tags. The active, semi-passive, and passive tags are different kinds of radio frequency identification tags. In a passive RFID tag, the range is less because it doesn’t have its own power supply. The RFID is an advanced technology, small in size, easy to use, and has a high memory capacity. The RFID reader consists of three components they are microcontroller, RF signal generator, and receiver of a signal generator. The RFID system operates on high, low, and ultra frequency ranges. The range of RFID tags is up to 10cms which is using the low frequency, the range of RFID tags is 10 to 15 meters which is using the ultra-high frequency, and the range of RFID tags is up to 1 meter which is using the high frequency. 1).
