Review of the market of different types of identification.
Identification is a reader that recognizes encoded signs and provides an opportunity to penetrate the protected object.
In our time, a large number of identifiers with various keys have already been developed.
Magnetic cards are probably one of the longest identifiers used. They are essentially plastic cards with built -in magnetic stripes with a recorded code. To carry out the passage, it is necessary to carry out a magnetic side of the card on the reading device.
They are quite strong and resistant to moisture and temperature changes, but, since this type of identification is contact, there is a fairly rapid abrasion of the magnetic surface, which requires regular replacement of such cards with new. At the same time, they have established themselves well where the replacement of cards is a common thing – these are hotels, parking lots, temporary employees of enterprises, etc. p.
The specifics of the arrangement of barcarts is as follows. In order to go to the facility, you should carry out a card on the reader, on the map itself is a bar-code closed by a special film.
A feature of reading the next identifier – Viganda maps – are chaotically located magnetic strips inside the card, they form a unique pattern, it is also an access code. To fake such cards is much more difficult than the options described above.
Proximitations of the map have proxy chips, which allow the device to read information from them remotely, that is, there is no need to carry out a card on the device, you can simply keep it in your pocket or bag.
The keys of “Touch Memory” are rounded, the chips are mounted in them, to pass to the object, it is required to bring the key to the reader. Unlike cards, this device has a longer service life.
The radio costs also belong to identifiers, but the principle of operation resembles the actions of remote controls, they are mainly used by guards.
The youngest and most promising direction in the development of this market segment is biometric technologies as a system of admission (according to facial features, voice, fingerprints). The main advantage, which is that the possibility of falsification of keys or card is excluded.
Much of what is available now, just a few years ago it seemed impossible and who knows can be in a few years, when repairing the apartment will strive to install not just reliable iron doors with a large number of castles, but also the identification system.
