The present dynamic of the business landscape prompts companies and individuals to constantly strive to improve their efficiency. One technology that has become increasingly popular in recent years is Radio Frequency Identification (RFID) labels. They are electronic tags that can be attached to various objects, providing a means of tracking and identifying them through radio waves.

RFID labels provide many advantages, including improved inventory precision and expedited supply chain management. However, the many available labeling options can pose a challenge when determining the most suitable one for your specific requirements. This guide will delve into these smart labels, including their functionality and the various types available.

How RFID Labels Work

RFID labels — or RFID tags or transponders — are small electronic devices that can be affixed to various objects, such as products, assets, or people. They feature an antenna and microchip that facilitate the transmission and reception of data via radio waves. They also serve as a mechanism for monitoring and identifying objects, enhancing inventory precision and supply chain management.

The labels operate based on the principle of wireless communication, allowing them to function without any direct physical link to the reader device. When a reader device is near the tag, it sends a radio signal picked up by the label’s antenna. This enables the microchip to receive power and transmit a unique identifier code back to the reader.

RFID tags are offered in various sizes to cater to different requirements. The size usually depends on the object it will be attached to and the read range necessary for the application.

Here are the three available dimensions and their respective uses:

  • Small-sized labels are suitable for tagging items like jewelry, documents, and compact electronic components.
  • Medium-sized tags are useful for tracking items like pallets, containers, and large machinery.
  • Large-sized labels are most appropriate for tracking fast-moving objects like vehicles and athletes.

Types of RFID Labels

RFID tags are available in various types, each designed with specific applications and operating requirements in mind. Listed below are some of the most commonly used types of labels:

Passive Labels

Passive labels are the most widely used due to their affordability and suitability for high-volume applications. They operate without a battery and instead rely on the electromagnetic field generated by the reader to power their microchip. This enables them to return the unique identifier code stored on the microchip to the reader.

Active Labels

Active labels have an embedded battery that powers both the microchip and antenna. This allows them to transmit signals over greater distances and with improved accuracy. Although they are more costly than the passive ones, their extended read range and higher accuracy make them useful for asset-tracking applications.

Semi-Passive Labels

Semi-passive labels combine features of both passive and active transponders. They have a built-in battery that powers the microchip but not the antenna. This allows them to provide a longer read range than passive labels while being less costly than active tags.

The Process of Making an RFID Label

The label’s production involves multiple stages: design, material selection, and printing. First, the design phase determines the position of the microchip and antenna and the shape and size of the tag. After that, the material selection requires selecting the substrate, adhesive, and conductive ink used for the antenna.

The printing process can be done using several techniques, including flexographic printing, screen printing, or digital printing. This usually depends on the design and the type of substrate being used. After printing, the RFID label is encoded with a unique identifier code that will be transmitted through radio waves.
