RFID technology. Everything about radio-frequency identification.

RFID (Radio-Frequency Identification) is a non-contact data exchange technology based on the use of radio-frequency electromagnetic radiation, which is used to automatically identify and register objects.

RFID System Components

Any RFID system consists of 3 basic components: RFID tags, RFID readers and software.

RFID-метки

RFID tags are miniature devices capable of storing and transmitting data. The tag memory contains a unique identification code. Some RFID tags have a memory that can be rewritten. When the tag enters the registration area, this information is received by the RFID reader.

RFID tag classification

By operating frequency:

  • LF 125-134 kHz (standard ISO / IEC 18000-2: 2009)
  • HF 13.56 MHz (standard ISO / IEC 18000-3: 2010)
  • UHF 860-960 MHz (standard ISO / IEC 18000-63 (C))

According to the material of the marking object:

  • For metal objects
  • For objects not containing metal
  • Universal

By execution:

  • Sticker
  • Integrated RFID tag (control (identification) mark, label, etc.)
  • Enclosed RFID tag

RFID Readers

RFID readers are devices that read information from tags or write data to them. They are connected to the accounting system and work autonomously.

Desktop RFID Reader

This type of reader is used for marking books or documents in libraries and archives, personalizing control (identification) mark during RFID-marking fur products, and authenticating products at points of sale. The RFID reader is installed directly at the workplace of the marker and is connected to the computer via the USB.

Mobile RFID Reader

Such devices are used in warehouses, in libraries and archives and are used in outdoor work, where there are no power sources. A mobile RFID reader is used for group accounting of objects, search and inventory of products, identification of objects in the field (service and repair work, product authentication).

RFID Portal

The main purpose of using portal RFID readers is the anti-theft function and theft prevention in libraries, stores, warehouses and other facilities. Portal RFID readers are used to identify vehicles, personnel records, moving people and objects (exhibitions, warehouses, factories).

Ceiling RFID Reader

It duplicates the functions of a portal RFID reader, but unlike it, it is installed in places with wide passages, behind a suspended ceiling, at objects of cultural value without interfering with the interior and structure of the building.

Software

Software accounting system that collects and analyzes information received from tags and links all the elements into a single system. Modern accounting systems are compatible with RFID technology and do not require special refinement.

Scope of RFID

Scope of RFID is constantly expanding. The technology is in demand in industries where control of the movement of objects, intelligent automation solutions, the ability to work in harsh operating conditions, error-freeness, speed and reliability are required.

In production, RFID is used to record raw materials, control technological operations, and ensure the principles of JIT/JIS and FIFO. RFID solutions in the production provide a high level and stability of product quality.

In the warehouse, RFID is used to track the movement of goods in real time, accelerate the processes of reception and shipment, increase the reliability and transparency of operations, and reduce the impact of the human factor. RFID solutions in stock provide protection against theft of products.

In retail sales, RFID systems track goods at the delivery stages, from the manufacturer to the counter. The goods are put on the shelf on time, are not stocked up in the warehouse and sent to those stores where there is high demand for them.

In the library, RFID helps to find in the repository and give out books to the reader, to prevent theft. Queues for extradition disappear. The time for selecting and searching for the desired publication is reduced, the inventory is simplified.

RFID tags are also used in marking fur coats and other fur products. Each product is marked with a Control (identification) mark with an RFID tag built into it.

Many areas of business and everyday life can be improved with RFID technology. The potential for RFID is enormous.
