RFID labels | RFID tagging

RFID. radio frequency identification) is a radio-based Automated Identification and Data Capture (AIDC) system that allows unique information to be read without physical contact (no optical line of sight) by means of tags worn or attached to objects. RFID technology began as a military solution to identify objects at a distance. Later, it moved into the commercial world with applications for tracking goods and storing data. As the technology has developed, RFID has become an important tool in logistics, trade and transport. Today, it is an integral part of the Internet of Things (IoT), used in medical, industrial and everyday consumer systems due to its reliability and accessibility.

Custom-designed RFID labels according to your needs – from design to finished product delivery.
RFID tagging in your production or logistics environment – printing and programming on site.
Automated data capture – integration with ERP and warehouse management systems.

What does an RFID system consist of?

RFID tagging allows you to quickly and efficiently read many tags at once without requiring line-of-sight.

RFID systems consist of:

RFID labels or tags are small chips with an antenna that store information.
RFID reader – a device that transmits and receives signals from the label.
Software – which manages the data collected and integrates it into common systems (e.g. ERP or warehouse management systems).

RFID technology in industry and business

The benefits of RFID technology are particularly evident in the following areas:

Logistics and warehousing: real-time tracking of goods, inventory automation.
Retail: faster stock-taking, anti-theft protection, more convenient self-service.
Healthcare: patient identification, tracking of equipment and medicines.
Industry and manufacturing: efficient parts and components management and automation of production processes.
Livestock: automated animal tracking and identification.

Retail trade

RFID tags allow companies to automate the control and accounting of goods from less than 1 metre away.

Inventory accuracy.
Omni-channel commerce – RFID helps stores offer ship-from-store, click-and-collect and faster self-service shopping.
Anti-theft – labels can act as components of an electronic security system (ESS).

Logistics and warehousing

RFID tags enable real-time monitoring and management of large-scale operations:

Automation of goods receipt and dispatch – RFID helps reduce labour costs and the risk of human error.
Tracking the movement of goods in the warehouse – a label on the scanner provides coordinated location of goods.
Labelling of packaging – e.g. sportswear in Decathlon distribution centres is labelled with special paper RFID labels.

Health protection

In the medical sector, RFID labels are used:

Patient identification (wristbands), reducing the likelihood of errors.
More expensive equipment and instruments for tracking.
Medication logistics to avoid the wrong medication being administered.

Some advanced systems use active RFID tags that can monitor environmental conditions such as temperature.

Technical aspects of RFID tagging

RFID tagging has the flexibility and applicability to a wide range of applications due to its technical characteristics. It is based on the transmission of radio waves between the tag and the reader, and the effectiveness of the system is determined by both the frequency range used and the type of RFID tag. RFID systems operate in three main frequency bands, each with its own specific advantages and limitations:

Low Frequency (LF: ~125 kHz)
Operating distance up to ~10 cm, provides reliable reading through water and dirt, less sensitive to metals. Commonly used in access control and livestock tagging.

High Frequency (HF: 13.56 MHz)
Reading distance up to ~1 m, average data rate. Uses an inductive coupling, works reliably with liquids and most materials. Popular in electronic passports, payment cards, libraries, public transport tickets.

Ultra High Frequency (UHF: 860-960 MHz)
Reading distance up to 10-12 m, fast data transmission, supports multiple tags simultaneously. Ideal for logistics, wholesale, warehousing and supply chain management.

Microwave frequency (2.45 GHz and above)
Used for semi-active tags, reading range ~6-10 m. Useful for high security or fast passage scenarios (e.g. car identification).

RFID labels and their types

Passive RFID labels – Passive RFID tags do not have an internal power source – they get the energy they need from the electromagnetic field emitted by the reader. This RFID tag is low cost, durable and extremely compact, making it widely used in product labelling, libraries, access control systems and consumer RFID solutions.

Active RFID labels – Active RFID tags have an internal battery that allows them to generate their own signals and be read from longer distances – up to several hundred metres. This makes them ideal for transport, logistics and high-value asset tracking. However, they are more expensive, larger and have a limited lifetime (due to the battery).

Semi-active RFID labels (BAP – battery assisted passive) have a small internal battery that is used only for signal amplification. Communication is still via the power of the reader. This is a compromise between range and cost – these tags are suitable when you need more reliable communication but don’t need all the features of an active tag.

Other RFID tag categories

Small Printable PCB Tag Labels – These RFID tags allow efficient identification and tracking of small electronic components during the manufacturing process. They can be adapted to both UHF and HF frequencies, depending on customer requirements.

RFID tags for inventory and stock management – this RFID tag is designed for efficient inventory management, allowing you to automate inventory and reduce the likelihood of errors in warehouse operations, thus optimising supply chain management.
Thermal RFID labels – suitable for use in high-temperature environments such as industry and laboratories. They are heat resistant, making them ideal for automotive, aerospace and electronics manufacturing processes.
UHF RFID adhesive labels for long distance reading – UHF RFID adhesive labels allow you to identify goods from a long distance (up to 12 metres). They are often used in the logistics, transport and warehousing sectors, where efficient and fast reading of goods over large areas is required.
RFID Logistics Shipping Tags – Tags specifically designed for the logistics sector, allowing real-time tracking of shipments and containers in both domestic and international supply chains, ensuring maximum security and operational accuracy.
Foreign passive UHF RFID cable labels – special passive RFID cable labels for cable identification and maintenance in infrastructure and data centres.

RFID tagging standards

RFID tagging is based on international standards that ensure compatibility between devices and systems. HF RFID complies with ISO 14443 or ISO 15693 standards, while UHF frequencies mainly use the EPCglobal Gen2 (ISO 18000-6C) specifications. The latter is widely used globally in logistics and supply chain solutions.

It should be noted that frequency use is regulated on a regional basis – for example, UHF RFID frequencies range between 865-868 MHz in Europe and 902-928 MHz in North America. International systems therefore require appropriate technical harmonisation.
