Chii chinonzi EAS?Inoita basa rekudzivirira sei?Paunenge uchitumira mune mall hombe, wakambosangana nemamiriro ezvinhu apo musuwo unonongedza pamusuwo?

Muwikipedia, inoti Electronic article surveillance inzira yetekinoroji yekudzivirira kuba muzvitoro, kupambwa kwemabhuku kubva mumaraibhurari kana kubviswa kwezvivakwa muzvivako zvehofisi.Special tags akaiswa kune zvekutengesa kana mabhuku.Aya ma tag anobviswa kana kuvharwa nevemabharani kana chinhu chatengwa nemazvo kana kutariswa.Pakubuda kwechitoro, sisitimu yekuona inoridza alarm kana neimwe nzira inozivisa vashandi kana yanzwa ma tag anoshanda.Zvimwe zvitoro zvinewo masisitimu ekuona pamusuwo wezvimbuzi zvinoridza alarm kana mumwe munhu akaedza kutora zvinhu zvisina kubhadharwa nazvo muchimbuzi.Pazvinhu zveukoshi hwepamusoro zvinofanirwa kushandiswa nevatengi, maaramu ewaya anonzi spider wrap anogona kushandiswa pachinzvimbo chetags.Pane zvimwe zvekuzivisa nezve EAS, kana uchizvifarira, just google.

Kune maviri anowanzo shandiswa marudzi eEAS - Radio Frequency (RF) uye Acousto magnetic (AM), uye mutsauko uripo pakati pawo ndeye frequency yavanoshandira.Iyi frequency inoyerwa mu hertz.

Acousto Magnetic masisitimu anoshanda pa58 KHz, zvinoreva kuti siginecha inotumirwa mukupuruzira kana kuputika pakati pe50 ne90 nguva pasekondi apo Radio Frequency kana RF ichishanda pa8.2 MHz.

Mhando yega yega yeEAS ine mabhenefiti, ichiita kuti mamwe masisitimu aenderane kune chaiwo vatengesi kupfuura vamwe.

EAS inzira inoshanda kwazvo yekudzivirira zvinhu kubva pakubiwa.Kiyi yekusarudza iyo chaiyo sisitimu yechitoro chako chekutengesa inosanganisira kufunga nezvemhando yezvinhu zvinotengeswa, kukosha kwazvo, chimiro chechimiro chenzira yekupinda uye zvimwe zvinotariswa senge chero ramangwana rekusimudzira kuRFID.
