The automatic identification system (ASI) of transport is organized on the basis of radio frequency contactless RFID tags.
The system is designed for automatic or automated vehicle identification when driving through a control point.
The system solves the following tasks:
Identification of transport in motion over long distances (from 2 to 30m).
Fully automatic registration of transport (without human participation in the identification process).
Simultaneous identification of several objects in the transport stream.
Using RFID technology can solve these problems. To do this, you must provide each edition with a label with a unique number. Labels can be made in any form and be attached in such a way that physical removal will be impossible. In this case, the appearance of the book will not suffer.
A label can contain a large amount of various information, for example, storage conditions, circulation and many other useful information. Installing radio frequency tags will allow you to keep records in the repositories, where there is a large number of books. This process, in contrast to working with bar codes, is not so laborious, since an RF scanner connected to a PC simultaneously reads several dozen marks at a distance of about one meter. Thus, the problem of thefts from libraries is solved. A radio frequency reader is installed near the exit from the reading room, and if you carry a book with a tag past it, information about the attempt to carry it out will go to a guard post or a librarian.

Asklepios Barmbek Hospital in Hamburg (Germany) unwittingly recalls fantastic films: patients with RFID wristbands allowing them to control their whereabouts, doctors using tablet PCs to record symptoms, nurses who record patient health indicators using PDAs. The staff of the emergency department monitor the flow of patients and the availability of the wards in real time, and X-rays are digitally transferred to the electronic patient record.
All of these are tomorrow's healthcare technologies that exist today at the Asklepios Barmbek hospital. The new hospital was included in the network of 95 medical institutions of the private organization Asklepios Hospital Group operating in the USA and Germany.
The Intel Solution Services group (a division of Intel) acted as a consultant for the implementation of IT solutions. Together with Asklepios and the Digital Health Group, Intel Solution Services is currently implementing about 18 pilot projects and coordinating IT service providers to translate the concept of an electronic hospital for the Asklepios network into practice.
This article once again addresses the issue of radio frequency identification technology, and addresses one of the most common standards in USA today.
The RFID theme, as we have said, is limitless. Today we will focus on a detailed review of another standard that is widely used in everyday life - the Philips Semiconductor Mifare® standard. Millions of people are already using this standard in NY...
Mifare® is an RFID object identification system with a reading and writing distance of up to 10 cm and conforming to ISO / IEC 14443, type A. It has an anticollision algorithm and allows simultaneous work with several cards in the reader field. Mifare® microchips are convenient for use in cards and various forms of transponders, which can be made in the form of key chains, coins, bracelets, etc. Consideration of the Mifare® architecture will start with the most common modification - Mifare® Standard. Map data structure The table shows the internal data structure of the map (sectors 2 through 13 are not shown - they are identical to the others).
In the last post, an overview article was published concerning proximity technology and its use in everyday life. Today we will continue this topic, dedicating the main part of the conversation to the international system of product identification GTAG.
In the last article, we mainly used the term proximity. In a broader sense and given the many new applications, the term RFID - Radio Frequency IDentification is becoming more and more common, which literally translates as "radio frequency identification." This term is more correct, as with the increase in the reading range of contactless tags, the meaning of the word proximity (close) begins to lose its original meaning.
The term GTAG is completely familiar only to specialists. It is derived from the phrase Global TAG, which can be translated as a “global label.” Why global? Because specialists of the whole world work on this standard, and this standard is proposed not as European or American, but as a global one. The main provisions of the standard have already been developed, the element base has been developed and the implementation of this technology has begun.
Things and technologies surrounding us have been changing very quickly lately, producing real revolutions in the way of life, although they usually pass “without noise and dust”. Not everyone thinks about it, taking everything as a natural change of day and night. But if you think about it, it’s very difficult to imagine today's world without these things. The Internet, mobile communications, GPS systems, handheld computers, digital photography and video shooting are only a small part of the iceberg. Today we are experiencing another such revolution, whose name is RFID.
... almost everyone knows
Yes, the phrase “contactless smart card” has been familiar to Moscow students and schoolchildren for several years, who use them extensively, for example, as travel tickets in the subway, and retirees in several districts of Moscow know the same card from a pilot project of a Muscovite’s social card. Many of those who use the Moscow and St. Petersburg metro on a daily basis also have such a map, as many of the municipal employees have it.
This card has a proper name - Mifare®. This name is clearly associated today with Philips, although it was developed by Micron, which was later purchased by Philips and became one of its divisions. We will talk about this card, its device and capabilities later, but for now let us recall once again the essence of the radio frequency identification technology (Radio Frequency IDentification) in order to understand its potential possibilities. Those who are already familiar with the basic principles can skip this section.

The number of publications on this topic does not decrease for several years. This is due to the rapid development of the RFID technology itself, the development of new frequency bands, the regular appearance of new products and new applications, where the technology of contactless identification (or radio frequency identification - Radio Frequency IDentification) allows us to solve problems previously impossible for hardware and software.
From chaos to order, or background
The radio frequency identification technology came into being about 20 years ago and the entire period was shaped at a pace ahead of computer technology. Particularly intense RFID has been improved in the last 5-7 years. This can be explained by two factors: firstly, the development of microelectronics allowed to implement many ideas previously unavailable for purely technological reasons, and secondly, there were standards, the use of which ensured compatibility of technical solutions from different manufacturers. Before considering the specific issues of the use of contactless identification in various areas of human activity, let us dwell on the general principles of RFID systems and regulatory documents that define and will determine in the near future the course of design ideas.
