Radio Frequency Identification Technology (RFID) is a technology of wireless data exchange via a radio signal between an electronic tag, which is placed on an object and read by a special radio-electronic device.
IT Co. offers services for creating RFID solutions for use in libraries, transport, logistics and other companies.
RFID system features
accounting and control of movement of goods, goods, etc.
control of movement and passage of control points by transport
access control
counterfeit protection
other.
The scope of application of RFID-systems is constantly expanding, besides the already existing methods of using RFID, which will be improved, there are many areas that are ready to adopt technology. The potential of using RFID is enormous.
Composition of RFID system
Tags (tags, transponders)
passive (read only information)
active (single write and multiple read or multiple read / write)
Readers (readers, antennas)
stationary
mobile
with different ranges
in room and outdoor performance.
System
writing data to tags
placing tags on goods
read data from tags
adding data to tags (about controls, etc.)
data collection and processing
transfer to other sites for control
reports and analytics.
The advantages of RFID systems compared to other identification methods
supported by major software providers (Microsoft, Oracle, SAP, etc.)
no contact or direct visibility needed
fast and accurate reading (close to 100% identification
good protection against environmental influences
passive tags have virtually unlimited lifespan
tags carry a lot of information
RFID tags are very difficult to fake.
RFID tags can be not only readable, but also with the ability to record information
the data on the RFID tag can be classified
the ability to simultaneously read multiple RFID tags at high speed.
Key RFID Applications
libraries and archives - search for literature, registration of received books and returned books to the library fund, inventory
trade and logistics - accounting and control of the movement of goods, goods, passing checkpoints by transport, inventory, etc.
public transport - traffic management, fare payment and passenger traffic optimization
security - control of access and movement of personnel in the territory and others.

A label is a small device for storing and transmitting information. It consists of a microchip and an antenna with which it transmits and receives information. There are tags that have a built-in power source (active tags), but the bulk of the tags used today do not have a built-in power source (passive).
A unique number and / or a certain amount of user memory is stored in the memory of the tag. When a tag enters the reading zone, this information is received by the reader (reader) - a device capable of reading and writing information in the tags, and transmitted to the computer for further processing.

Barcode vs. RFID tag
In order to optimally manage the supply chain and production process, it is necessary to track the movement of each unit of goods, sometimes every detail. Modern technologies make this task easier.
Today, there are many methods of auto-identification, based on the principle of contactless reading of information.
The most popular and common of them is bar coding. However, it is rapidly catching up with radio frequency identification (RFID). This technology is successfully used by the world's largest retail chains, such as Wal-Mart, Target and Tesco.
RFID is a generic term for technologies that are used to automatically identify radio wave objects. They are emitted by special marks placed on identifiable items. RFID allows you to track the location of items, boxes and pallets as they move through the supply chain to the consumer. Readers (RFID readers) collect information about each object into a central database.
There, code tags are identified with information about identifiable items, as a result of which the user of the system can at any time receive an exhaustive report on the relevant subject.
RFID technology provides higher speed and accuracy of information transfer in the supply chain than bar coding.
This difference is particularly noticeable in organizations with global supply chains and an extensive distribution and retail network.
More extensive RFID information collection capabilities ensure that there are no discrepancies in the data and greater transparency in the logistics scheme. This contributes to cost reduction and more efficient operation.
The goal of any retail store is to maximize customer satisfaction by maintaining optimal inventory levels while reducing operating costs. The key points of trading are receiving goods, reconciling and setting prices, moving goods to the sales area from the back room.
Successful trading can be hampered by the following problems:
• the goods have not entered the store
• the product entered the store, but did not hit the storefront on time
• the goods are already on display, but it is not clear whether it can be sold
To avoid this, many retailers invest in technology solutions such as enterprise resource planning (ERP) or warehouse management systems (IMS).
But they are based on processing a large amount of data, so reliable sources of information are needed for normal operation. These sources are barcodes and
