RFID Tags: What They Are and What They Can Be Used For
Trace ID’s expert guide to transforming your processes with RFID technology.
In the digital age, RFID (Radio Frequency Identification) technology has become an essential tool for automation, inventory management and product traceability. With more than 10 years of experience in technology marketing and RFID solutions, Trace ID is at the forefront, offering high quality RFID tags developed using advanced bonding and converting processes. These techniques guarantee maximum durability and performance, ensuring that each tag is perfectly adapted to the demands of the environment in which it is used.
What is RFID Technology?
RFID technology enables the identification and tracking of objects without the need for physical contact or direct line of sight. This is achieved through wireless communication between a reader and an RFID tag, which contains a chip and an antenna. By transmitting information via radio waves, complete traceability along the supply chain, from raw material to the end consumer, is made possible. The digitisation and automation offered by RFID reduces errors, optimises processes and facilitates real-time decision making.
Fundamental Components of an RFID Tag
An RFID tag is made up of three essential elements, each optimised with bonding and converting processes to ensure quality and resilience:
RFID chip:
This is the “brain” of the tag. It stores data and manages communication with the reader. The chips can have different memory capacities and security levels, adapting to applications ranging from basic identification to high traceability and security systems.
Antenna:
Connected to the chip, the antenna captures the energy of the electromagnetic field emitted by the reader and transmits the signal. Thanks to advanced converting techniques, the antenna design is optimised to maximise range and efficiency, even in environments with electromagnetic interference or in the presence of metallic materials.
Substrate or Support Material:
This component binds and protects both the chip and the antenna. We use high-strength materials, subjected to rigorous bonding processes that ensure a solid and durable bond, even in extreme conditions such as industrial or cooling environments.
The perfect combination of these elements forms the RFID inlay, the technological core that enables accurate wireless communication and full traceability.
RFID Label Types
RFID tags are classified according to their power source and activation mode:
Passive Tags:
They have no internal battery and are activated by the energy of the electromagnetic field generated by the reader. They are ideal for short to medium range applications (up to 15 metres) and stand out for their low cost, being widely used in traceability systems in logistics and retail.
Active Tags:
They incorporate an internal battery that allows them to transmit signals continuously, reaching much greater reading ranges (up to 100 metres or more). They are ideal for real-time monitoring and control of assets in large infrastructures.
Semi-Active Tags (Semi-Passive):
Combine external signal activation with an internal battery that boosts the chip’s response. They offer a balance between cost and performance, providing greater accuracy in traceability systems without the high cost of active tags.
Bonding and Converting Processes: The Basis of RFID Label Quality
At Trace ID, our bonding and converting processes are fundamental to ensuring that every RFID tag meets the highest quality standards:
Bonding:
This process focuses on the perfect bond between the chip and antenna, ensuring a robust connection that withstands harsh conditions. Quality bonding is essential to avoid communication failures and ensure the integrity of the stored data.
Converting:
Refers to the transformation of raw materials into final products through cutting, laminating and printing techniques. Converting allows labels to be customised in terms of shape, size and design, adapting to the specific needs of each sector and application.
These processes not only optimise strength and durability, but also enable full customisation of RFID tags, expanding their applications in a variety of environments.
Featured RFID Technology Applications
The versatility of RFID technology and the quality of RFID tags enable their application in a wide range of industries. Some of the most prominent applications are detailed below, with a full development and definition of each:
