Electronical Article Surveillance (EAS) enables store personnel to focus on sales job and customer service. EAS systems consist of antennas at store exit and security detectors attached to merchandise that will result in alarm when placed between antennas, attached or not deactivated. As a result there is professional service and friendly atmosphere in the shop.
EAS enables protecting wide range of merchandise. The selection of equipment is specific based on the products’ range sold in the shop. Most common security elements are tags attached with a needle on clothing, single-use labels applied to merchandise and safety boxes for CD, DVD and other high value items, as well as the sound alarm devices.
EAS systems may have different system combinations and technologies.
There are three different technologies offered by Pristis based on working principle:
AM (Acusto Magnetic)
RF (Radio Frequency)
EM (Electro Magnetic)
In general preference of technology is based on following thinking:
AM – first choice, delivers best performance when used in hypermarkets, boutiques, hardware (DIY) stores, drug stores, cosmetics etc. 
EM – used in special cases in libraries, drug stores.
RF – used in special cases when customers are using RF technology, price-sensitive clients (small boutiques)
Advantages of AM technology are:
- Latest technology
- Wide exits
- High detection rate
- Detection inside shop trolley
- High variety of security elements
- Leader of source tagging
