RFID Tags & The Future of Labeling
This week’s #MovieMonday is a 2-4-1. We have two quick-hitting videos this week, as our in-house RFID aficionado, Bjorn Wangensteen, sits down to explain to us the benefits of RFID tags and how they will soon become the new normal in the future. (Be sure to watch video #2! We think you’ll find it interesting).
Radio Frequency Identification (RFID) technology has been steadily gaining traction across various industries, transforming how we track, manage, and secure items. RFID is often used in applications where traditional barcode technology was previously or still is used.
In our first video, we’ll quickly explain how RFID works and the advantages is poses compared to regular barcode technology.

How RFID Works
RFID systems consist of three main components:
1. RFID Tags: These are small devices that can be attached to or embedded in objects. Each tag has a microchip that stores information and an antenna that transmits this information to an RFID reader.
2. RFID Reader: This device emits radio waves and receives signals back from the RFID tags. The reader converts the radio waves returned from the RFID tag into digital information that can be processed by a computer system.
3. Antenna: This is responsible for transmitting and receiving the radio signals between the RFID tag and reader.
The RFID Process
When an RFID tag comes within the range of an RFID reader, the reader emits an interrogation signal. In the case of a passive tag, the tag’s antenna gathers energy from this signal and powers the microchip, which then transmits the tag’s information back to the reader. For active tags, the internal battery powers the response. The reader captures this information and forwards it to a central database where it can be processed and analyzed.
Future Applications of RFID
The versatility and efficiency of RFID technology have led to its adoption in a wide range of industries, and its use is expected to grow significantly in the coming years. Here are some key areas where RFID is set to make a substantial impact:
1. Retail and Supply Chain Management
RFID can revolutionize inventory management by providing real-time visibility into stock levels and product locations. This enables retailers to reduce out-of-stock situations, minimize shrinkage, and optimize supply chain operations.
2. Healthcare
In healthcare, RFID can be used to track medical equipment, manage pharmaceutical inventories, and even monitor patient movements within a hospital. This improves operational efficiency and enhances patient safety by ensuring that the right equipment and medications are available when needed.
3. Transportation and Logistics
RFID technology can streamline logistics operations by enabling precise tracking of goods throughout the supply chain. This can lead to faster delivery times, reduced errors, and lower operational costs. As e-commerce continues to grow, the demand for efficient logistics solutions will drive further adoption of RFID in this sector.
4. Security and Access Control
RFID is widely used in access control systems to manage entry to secure areas. In the future, we can expect to see more sophisticated applications of RFID in security, including integration with biometric systems and advanced encryption techniques to enhance security measures.
5. Smart Cities and IoT
As cities become smarter and more connected, RFID will play a crucial role in managing urban infrastructure. From tracking public transport assets to monitoring waste management systems, RFID will help cities operate more efficiently and sustainably. Additionally, the integration of RFID with the Internet of Things (IoT) will open up new possibilities for automation and data-driven decision-making.
These future applications all sound like no-brainers to me, but how about something a little more outside the box?
In video #2, Bjorn discusses a unique (and maybe scary?) RFID application that was already adopted several years ago in Sweden:
What do we think? Are the Swede’s just ahead of the game? Or are they embracing an Orwellian dystopia?!
Time will tell, I guess.
