RFID Tag (Radio Frequency Identification Tag):
Definition-What does RFID Tag mean?
A RFID tag is an electronic digital tag that trades information with a RFID reader by means of radio-waves.
Most RFID tags consist of at least two primary parts. The very first is an antenna that receives radio-frequency (RF) waves. The second is an integrated circuit (IC) used to process and store data as well as to modulate and demodulate radio waves transmitted/received  by the antenna.

A RFID tag is also referred to as a RFID chip.

Although RFID tags have very similar applications to bar codes, they are significantly more advanced. For example, reading data from a RFID tag doesn't require line-of-sight and could be performed more than a range of a few meters. This actually also suggests that only one tag can assist several readers at the same time, when compared with only one in case of a bar code tag.
In the context of RFID technology, the word “tag” also includes cards and labels. The type of tag depends on the object or body to that the tag is connected. RFID systems can function in Low Frequency (LF), High Frequency (HF) or Ultra High Frequency (UHF). Hence, tags can also vary with regards to the frequencies on which they function.
These tags could be attached with just about any object. Even though the typical targeted objects are containers, construction materials, bag-gages, apparel, bottles and laundry, additionally they can be attached to humans, animals, and vehicles. Some RFID tags are also suitable for outdoor based applications.


These are created to withstand natural and incandescent vibration, shock, light, rain, oil, dust and other tough conditions. They're usually passive in that to operate, they don't need battery packs and can function 24/7 without risk of energy loss. These kinds of heavy-duty tags are often attached with cargo containers, light-weight rail cars for cargo tracking, trucks, vehicle tracking, fleet management, supply container tracking, and vehicle identification among others.
