In wikipedia,it says Electronic article surveillance is a technological method for preventing shoplifting from retail stores, pilferage of books from libraries or removal of properties from office buildings. Special tags are fixed to merchandise or books. These tags are removed or deactivated by the clerks when the item is properly bought or checked out. At the exits of the store, a detection system sounds an alarm or otherwise alerts the staff when it senses active tags. Some stores also have detection systems at the entrance to the restrooms that sound an alarm if someone tries to take unpaid merchandise with them into the restroom. For high-value goods that are to be manipulated by the patrons, wired alarm clips called spider wrap may be used instead of tags.There has more introduce about EAS,if you are interested in it,just google.

There are two commonly used types of EAS – Radio Frequency (RF) and Acousto magnetic (AM), and the difference between them is the frequency at which they operate. This frequency is measured in hertz.

Acousto Magnetic systems operate at 58 KHz, which means a signal is sent out in pulses or bursts between 50 and 90 times a second while Radio Frequency or RF operates at 8.2 MHz.

Each type of EAS has benefits, making some systems more suited to specific retailers than others.
