In the basis of the anti-theft systems may lie a variety of technologies. Thus, radio frequency technology is designed for identifying of radio contours that are located in fixed on the goods security elements. This equipment works in very sensitive to noise and interference range so that the average response factor is about 85%. Anti-theft acoustomagnetic technology systems give the minimum percentage of erroneous detection, because the range in which they operate is less exposed to various noises and interferences. Another variety is Anti-theft electromagnetic technology systems. Working expenses for electronic tags are relatively small, which leads to their widespread use in stores with a high trade turnover. The most comprehensive range of hard sensors and security labels are recognized by the anti-theft radiomagnetic technologies systems, which combine the characteristics of electromagnetic and radio frequency technologies. Detection rates, which mean the safety factor for pick-up, in anti-theft systems can vary a lot, as for systems with acoustomagnetic technology they are on average are about 95%, for radiomagnetic systems - from 95 to 98%, and for radio frequency from 80 to 85%. Apart from the technologies used in such equipment, anti-theft system must be durable and resistant to mechanical damages, have a long service life and reliable to perform their functions.
