Getting to know the technologies around us is very important. Radio Frequency Identification (RFID) is one of the most frequently used technologies. Even when we don’t realize it, we see and use RFID readers and RFID tags in our everyday lives. Keep reading if you want to learn more about the technology, its benefits, and possible disadvantages.
How Does RFID System Work
RFID System uses wireless technology to transfer the collected data. The system has two main pieces that integrate with each other. An RFID tag and a reader. In order to explain reader and tags, the concept of how it collects data has to be understood.
RFID systems use radio waves to transfer the data. RFID Tags collect the data from the attached devices, and the reader transfers the data to a database.
In our daily lives RFID technology is often used. We can see them in:
- Credit cards (the RFID helps you pay without contact).
- Cargo and mail packages who have barcodes on them.
- Metro, bus and other transportation cards.
- Pets who have microchips attached to them.
What Role Does RFID Play in Waste Management
RFID Systems are very beneficial during waste management operations. Controlling the location of vehicles and assets, identifying task completion, and detecting accidents before they happen are achievable with RFID systems. RFID is installed in waste containers and used for the optimization of waste operations. The collected data can be transferred and stored in a dashboard effortlessly.
With RFID systems, managers will have complete control over the operations. Tracking vehicles and assets are effortless because every tag will be identified to a container, so the information of every container will be transported accurately to the dashboard.
RFID systems can improve your operational efficiency even in the short term. If you have any questions on what is RFID reader and Tag, and how it can integrate with your waste management operations you can check here.
Can You Recycle RFID Tags?
RFID tags are made from different materials, and when their lifespan comes to an end, like most products, they need to be recycled.
The critical component of RFID tag recycling is the sorting process. If you think of the tag, it is mainly made from polyethylene terephthalate. PET is a type of plastic that can be easily recycled. However, the challenging part of the tag recycling operation starts after this.
Every RFID tag has a metal antenna inside it that helps communicate data. When the material separation or sorting process starts, the antenna must be removed manually when considering the high number of tags; this procedure can be challenging. (Source )
Passive tags are much easier to decompose compared to active tags. Passive RFID tags are not that complex when it comes to their internal structure. On the other hand, recycling is crucial because it is often powered by lithium batteries, especially for active tags.
Are RFID Tags/Readers Dangerous for the Environment
RFID systems are a helping hand in today’s world, but how sustainable and healthy are they? RFID tags communicate when it comes into contact with the reader’s electromagnetic field. The RFID readers can transmit waves in three frequency bands. These are 125 kHz for very low frequency (LF) readers, 13.56 MHz for high-frequency (HF) readers, and 900 MHz for ultra-high-frequency (UHF) readers.0p*
The wave frequencies are the main criteria for the environmental and human risks. Usually these frequencies do not pose any danger for humans, however for minimum harm it is advised to stand at least 20 cm away from the RFID readers.
