Why does RFID technology conquer more and more widespread markets, penetrating the most diverse areas of activity where fast and reliable identification of items is required? Because it has a number of advantages, in particular:
RFID tags do not need contact or direct visibility;
RFID tags are read quickly and accurately (approaching 100% identification);
RFID can even be used in aggressive environments, and RFID tags can be read through dirt, paint, steam, water, plastic, wood;
passive RFID tags have virtually unlimited lifespan;
RFID tags carry a large amount of information and can be intelligent;
RFID tags are almost impossible to fake;
RFID tags can be not only for reading, but also for recording a sufficiently large amount of information.

Identification of containers and other group cargoes is relevant for their dispatch during transportation. RFID allows you to greatly simplify and automate the process of cargo management. The requirements for cargo identification systems are numerous. This is a significant (up to several meters) reading range of identifiers, providing anticollision (reading several tags at the same time), and the work of tags on metal surfaces. In addition, from the point of view of the organization of the technological process, it is advisable to use tags with the possibility of rewriting information so that certain states of the process can be quickly displayed in the cargo ID. To solve this problem, it is advisable to use passive systems in the range of 800-900 MHz with special design labels. For cargo handling, stationary readers with a range of up to 4 ... 5 meters can be used, as well as hand-held scanners, for example, based on a PDA. Such readers have a read range of up to 30 ... 50 centimeters, and if they are connected to the network (for example, using wireless technologies like Wi-Fi), they ensure the “online” operation of the system as a whole.

Most of the cards used in access control systems (ACS) - contain a fixed identification number, which is “stitched” at the factory and is available only for reading. With the use of smart cards, you can use both its serial number and data recorded in the non-volatile area. The organization of access control systems based on contactless smart cards allows you to increase the level of security of the system, virtually eliminating the possibility of card falsification. Rewritable cards exist with both open protocol and cryptography. Entering a new code into the crypto-protected area can be accomplished with the help of a special utility, and, further, the reader, which is also transferred to the operation mode with crypto-protected areas, will only apply to this area to read the code. In this area you can bring any combination of numbers and letters. To change the access codes to the protected area and enter them into the readers, a special master card is created (also with the help of the utility), after which you can use the computer to issue cards with new keys. When working with such cards and readers, you can change the access codes in the system even daily.
