RFID technology is not very new to tech lovers, yet many of us unknowingly use it when we issue parking tickets or are using biometric passports. This smart technology has sneaked into our lives in significantly less time, and here is a quick overview of the RFID process and its impact on IoT technology.

What is RFID?

Radio Frequency Identification, commonly referred to as RFID, is a wireless connection between devices operating on the principle of electromagnetic coupling with the radio region of the EM spectrum. This process allows the electromagnetic waves to identify an object, thing or animal or seamlessly connect devices.

This technology is similar to a barcode scanner, but we can consider it a more advanced version of it as it can scan multiple tags together. RFID process doesn’t require the tags to be physically in front of the scanner; instead operates within the limits of ranges. Powerful RFID sensors and receivers can work for longer distances depending on the type of tech and devices in focus.

How Did This Technology Start?

The process of RFID can be traced back to World War II, when the famous Theremin’s Thing used the early version of this seamless and wireless communication. The presence of an antenna within the seal, which was called “The Thing” allowed the Soviets to listen to the private conversations of US ambassadors, merely through the activation of radio waves.

Apart from this, RFID principle was deployed in tagging of railway coaches. In a few years, the official patent and the name came into being by Charles Walton in the year 1983.

The Progress of RFID Technology

Over the years, RFID was a field that did not receive much attention due to limited research and its usage was limited to very few sectors. The past 20 years did not see much of an evolution in this promising tech, but the latest research and investments targeted toward this process have brought it into the limelight.

In recent years, big names like Adidas and Decathlon invested in RFID and have marked a significant increase in productivity and sales, making this technology a common name in the present retail and technological market.

The RFID system in recent times is based on three components: Antenna, Transceiver and a Transponder. The antenna and transceiver together are called RFID readers and use radio waves to transmit signals to the nearby RFID device. RFID tags carried by another RFID-enabled gadget or device activate the RFID readers and allow them to carry out information or data exchange without being in touch physically.

RFID and Its Impact on IoT

Internet of Things or IoT is everywhere around us, and fortunately, the evolution of RFID has synced with the evolution of IoT. The major component of IoT that benefits a wide array of businesses is the “Sensors”. The sensors can predict the temperature of rooms, limit access of people, and detect things through AI-induced technologies that can never be detected manually.

Be it healthcare, aircraft or retail market, the sensors are being extensively used, and when combined with the RFID tags, the power of IoT is doubled, widening its applications and usage.

RFID can be coupled with the IoT technology and can be used for a variety of purposes like:

· Efficient asset tracking and management of all the processes in offices and other sectors.

· Tracking and identification of vehicles and even monitoring the vehicle speed.

· Monitoring of activity and temperature in the construction sector and housing boards.

· Movement monitoring in traffic and road activity.

· Tracking patients’ condition and their activity and assisting the medical care industry.

The RFID tags are useful components of all the devices that enable them to form instant communication with other devices. The IoT is intent on making everything smart in our homes, offices and building and RFID technology is an integral part that is widening the scope and making the unimaginable things true in this smart tech era.
