A common term to hear when working in any company that’s adapting to the Fourth Industrial revolution (Industry 4.0) would be ”RFID” or “Radio Frequency Identification”. With the word RFID appearing almost everywhere, it’s almost a given that an average person would have heard the term at least once in their lives. To many of us working in the visibility solutions field, RFID is a basic concept that is understood by all of us at PT. Duta Kalingga Pratama, but beyond us, does everybody else know the inner workings of Radio Frequency Identification (RFID) and how it actually works? Or how it benefits industries other than ours? In this article, we’ll discover what is defined as Radio Frequency Identification (RFID) and how it affects the world around us today.
Definition of RFID
According to Amsler and Shea (2021), RFID (or Radio Frequency Identification) is defined as, “a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.”
How an RFID Works
Normally, an RFID system is made up of three integral components: an antenna, a transceiver, and a transponder. An RFID reader (sometimes known as interrogator) is when the functions of the antenna and transceiver are combined. On the other hand, the transponder is typically the RFID tag. The cycle of operation begins when the RFID reader’s radio waves detect and activate the RFID tag, which responds by emitting another wave to the reader which will be translated as data. Simply enough, the range of detection for RFID tags depends on factors such as the type of tag and reader used, how strong the RFID frequency is, and any resounding interference in the surrounding environment (or from other RFID tags and readers, which results in conflicting radio waves). (Amsler and Shea, 2021)
What are the types of RFID systems?
Depending on the choices of country or company using the system, they can use one of the three main types of RFID systems: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF). Microwave RFID is also available. (Amsler and Shea, 2021)
Low-Frequency RFID systems: These range from 30 KHzto 500 KHz, though the typical frequency is 125 KHz. LF RFID has short transmission ranges, generally anywhere from a few inches to less than six feet.
High-Frequency RFID systems: These range from 3 MHzto 30 MHz, with the typical HF frequency being 13.56 MHz. The standard range is anywhere from a few inches to several feet.
Ultra High-Frequency RFID systems: These range from 300 MHz to 960 MHz, with the typical frequency of 433 MHz and can generally be read from 25-plus feet away.
Microwave RFID systems: These run at 2.45 Ghzand can be read from 30-plus feet away.
Where RFID can be seen today
As stated earlier, RFID is extremely common to find in today’s world, it could be found in our Citizen Identification Cards (KTP) and E-Passports, it could be seen on hotel (or generally locked and secured) room doors, and even as simply as your E-Money / Flazz Cards for speedy (tap-and-go) transactions. A list of some industries using RFIDs can be seen below and do note that these do not account for all uses:
Pet and livestock tracking (Usually found through an identification chip on their ears)
Retail inventory management and control (Security Tags on valuable goods)
Asset tracking and equipment tracking
Shipping cargo and supply chain logistics
Vehicle tracking (GPS)
Customer service and loss control
Improved visibility and distribution in the supply chain in the Manufacturing Industry
Access control in security situations (Keycards for gated entryways)
Healthcare and Hospitality
tap-and-go credit card payments (Mandiri E-Money or BCA Flazz)
(Amsler and Shea, 2021)
RFID for the Future
In recent times, RFID systems are being used more frequently to support growth and expansion of the internet of things. By combining these systems with other input devices such as smart sensors or GPS technology, more data can be extracted through the wireless transmission of radio waves, which include variables such as temperature, movement and location. (Amsler and Shea, 2021)
To conclude, RFID (Radio Frequency Identification) is a revolutionary addition to the list of breakthrough technologies seen today. From its many current uses in the day-to-day operations of many industries, it’s important that we continue cultivating the technology of RFID and increase its effectiveness, efficiency, and most importantly security as we move on into the era of wireless automation, otherwise known as the Fourth Industrial Revolution (Industry 4.0). PT. Duta Kalingga Pratama vows to provide our partner’s RFID solutions to support the technology’s growth and expansion worldwide. To see what RFID products we currently have in stock, click here!
