What is an RFID-taggar?

RFID-taggar is also called RFID tag, or Radio Frequency Identification tag, is a small electronic device with an integrated circuit chip and an antenna. It uses radio waves to wirelessly transmit data between the tag and an RFID reader. RFID tags come in different forms like adhesive labels, cards, key fobs, or embedded within products. They are commonly used for identification, tracking, and inventory management in various industries.


RFID tags offer several advantages. Firstly, they operate without requiring physical contact with the reader, allowing for convenient and efficient data transfer. Secondly, they have the capability to store and update information, making them suitable for dynamic environments.

Additionally, RFID tags have a long read range, eliminating the need for individual scanning and speeding up processes like inventory management or access control.

Lastly, RFID tags can be designed to be durable, withstanding harsh environmental conditions in industries or outdoor settings.

RFID technology is versatile and widely used across different sectors for its efficiency and convenience in data transmission and tracking. they can also be used to track vehicles, pets, and even patients with Alzheimer’s disease.

How do RFID-taggars Work?

RFID tags operate by transmitting and receiving information through an antenna and microchip, also known as an integrated circuit, or IC. The microchip on an RFID tag can be programmed with user-specific information.

There are two primary types of RFID tags: battery-operated and passive. Battery-operated tags, also known as active RFID tags, have an onboard battery as a power source. Passive RFID tags, on the other hand, do not have a built-in power supply and instead utilize electromagnetic energy transmitted from an RFID reader.

Passive RFID tags use different frequencies to transmit information, such as low frequency (125–134 KHz), high frequency (13.56 MHz, including Near-Field Communication, or NFC), and ultra-high frequency (865–960 MHz). The frequency used affects the range of the tag.

When a passive RFID tag comes into the range of an RFID reader, the reader transmits energy, which powers the tag’s chip and antenna. The tag then relays information back to the reader, which is subsequently sent to an RFID computer program for interpretation.

Passive RFID tags can be categorized as inlays or hard tags. Inlays are thin and can be attached to different materials, while hard tags are made of more durable materials like plastic or metal.

In contrast, active RFID tags use frequencies like 433 MHz or 915 MHz to transmit information. They consist of a tag, an antenna, and an interrogator. The battery in an active RFID tag typically lasts 3-5 years, and when it depletes, the entire unit needs to be replaced since the batteries are not replaceable.

Active RFID tags can be further classified as beacons or transponders. Beacons emit regular information pings and can be read from several hundred feet away. Due to frequent data output, their battery life tends to deplete faster. Transponders, similar to passive RFID tags, require a reader to transmit information. They only activate when in the vicinity of a reader, making them more energy-efficient compared to beacons.

Active RFID tags are ideal for real-time tracking purposes, such as tolling and live vehicle tracking applications. These tags continuously emit a signal, allowing for up-to-the-minute tracking information. Although they are more expensive than passive RFID tags, they offer a significant advantage with their long read range, making them suitable for specific applications.

In contrast, passive RFID tags are a cost-effective option, typically priced around 20 cents each. They are commonly used in supply chain management, race tracking, file management, and access control applications. While passive tags do not require a direct line of sight to the RFID reader, their read range is shorter compared to active tags. However, they make up for this limitation with their small size, lightweight nature, and potential longevity.

Active RFID tags are designed to be larger and more durable than passive tags, making them well-suited for applications that require ruggedness. They find use in toll payment transponder systems, cargo tracking applications, and even in devices used to track individuals. Given their durability and ability to withstand harsh conditions, active RFID tags are preferred in scenarios where robustness is crucial.

The Advantages and Disadvantage of RFID-taggars

Advantages of RFID Tags

Using RFID tags offers several key advantages:

  1. Increased efficiency: RFID tags enable fast and accurate tracking of items, improving operational efficiency.
  2. Improved accuracy: Unlike barcodes, RFID tags can be read even when hidden or obstructed, enhancing data accuracy.
  3. Reduced labor costs: RFID tags allow for automatic reading, eliminating the need for manual scanning and reducing labor expenses.
  4. Enhanced security: RFID tags can be encrypted and programmed with unique identifiers, making it difficult for counterfeits or unauthorized items to enter the supply chain.
  5. Real-time tracking: RFID tags provide real-time data on item location and movement, facilitating better inventory management and supply chain optimization.
  6. Durability: RFID tags are more resilient than barcodes, maintaining readability even in adverse conditions and over extended periods.

Overall, RFID tags offer significant benefits for businesses seeking to enhance supply chain management and inventory tracking processes.

Disadvantages of RFID Tags

However, there are some disadvantages associated with RFID technology:

  1. Security issues: RFID tags lack the ability to differentiate between readers, potentially allowing unauthorized access. Scammers could exploit this vulnerability by gathering sensitive information without the person’s knowledge. Additionally, linking RFID tags to credit cards poses a risk of financial theft and fraud for consumers.
  2. Technological issues: The absence of global or industry standards for RFID tags restricts their interoperability. Radio frequency-based RFID systems are susceptible to disruption or jamming, reducing their reliability and usability. Such issues can lead to increased wait times and decreased productivity in retail and warehouse settings.
  3. Technology issues: RFID systems may encounter problems such as signal collisions when multiple readers overlap or interference from metal, water, or magnetic fields in the surroundings.
  4. Set up issues: The implementation of an RFID system can be time-consuming and labor-intensive. Testing different hardware and tag systems to find an optimal solution often takes months. Additionally, apart from the cost of the RFID system components, the increased time and labor investment translate to higher expenses.

These drawbacks have prompted many businesses to opt for barcodes, which offer simplicity and widespread acceptance in data collection and inventory control.
