Electronic article surveillance (EAS) is a technological method for preventing shoplifting from retail stores or pilferage of books from libraries. 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. For high-value goods that are to be manipulated by the patrons, wired alarm clips may also be used; these, being less common and technologically less mysterious, are not covered by this article.

Electronic article surveillance tags: Acousto-magnetic (top) and RF (bottom).

Types of EAS

There are several major types of electronic article surveillance systems :

  • Magnetic, also known as magneto-harmonic
  • Acousto-magnetic, also known as magnetostrictive
  • Radio frequency
  • Microwave
  • Video surveillance systems(to some extent)

Does that antitheft thing, that goes off if you stole something, damage headphones?
Q. Supposedly its called a Electronic Article Surveillance (EAS) and every time i walk pass one, my headphones start making a high pitched sound. so i was wondering whether or not this will damage the performance of my headphones, so i can avert my headphones over them. Thanks in advance for your replies.

A. No. It will not damage your headphones. The power is not sufficient to do so. Also, it's RF and your headphone is made for AF frequencies. Now maybe whatever your headphones are attached to is sensitive to the RF. Again, though, it's merely interference and the power is not sufficient to cause damage.

Q. LONDON (Reuters) - A jury convicted a man on Friday of aiding fighters in Pakistan and Afghanistan as an accomplice to a man who admitted plotting to kidnap and behead a Muslim soldier from the British army. (Advertisement) The beheading plot caused a security alert in Birmingham. Ringleader Parviz Khan, 37, admitted the plot at the beginning of the trial last month and three other men admitted other terrorism offences. A jury on Friday found a fifth member of the group, Zahoor Iqbal, guilty of helping terrorists abroad. He was not charged with a role in the beheading plot, but was accused of working with Khan to supply equipment to fighters on the Pakistan-Afghan border battling Western troops. The men were "actively assisting… [cont.]

A. Deportation is the only answer in our soft touch country, along with all family members. let all terrorist go to the country they want to defend whilst living in the uk on benefits. these so called immigrants should be better vetted before allowed in any country not just the uk.. but because the government in the uk are pleasers of immigrants instead of its own nation. more and more brits are moving to other country'S but the main factor is they are willing to earn a living not off the back of other country'S
