Iyini i-EAS?Idlala kanjani indima yokuvikela?Lapho uthumela enxanxatheleni yezitolo enkulu, ingabe uke wahlangabezana nesimo lapho umnyango ukhiya emnyango?

Ku-wikipedia, ithi ukubhekwa kwe-Electronic article kuyindlela yobuchwepheshe yokuvimbela ukweba ezitolo, ukuntshontshwa kwezincwadi emitapo yolwazi noma ukususwa kwezakhiwo ezakhiweni zamahhovisi.Omaki abakhethekile bagxivizwa kokuthengiswayo noma ezincwadini.Lawa mathegi ayakhishwa noma acishwe omabhalane uma into ithengwe kahle noma ihlolwe.Ekuphumeni kwesitolo, isistimu yokuthola ikhala i-alamu noma ixwayisa abasebenzi uma izwa omaka abasebenzayo.Ezinye izitolo zinamasistimu okubona emnyango wezindlu zangasese ezikhala i-alamu uma othile ezama ukuthatha okuthengiswayo okungakhokhelwa aye nakho endlini yangasese.Ezimpahleni zenani eliphezulu okumele zikhonjwe abaxhasi, iziqeshana ze-alamu ezinentambo ezibizwa ngokuthi ukugoqa kwesicabucabu zingasetshenziswa esikhundleni samathegi.Kunesethulo esiningi mayelana ne-EAS, uma uthanda, ku-google nje.

Kunezinhlobo ezimbili ezivame ukusetshenziswa ze-EAS - I-Radio Frequency (RF) ne-Acousto magnetic (AM), futhi umehluko phakathi kwazo yi-frequency ezisebenza ngayo.Le mvamisa ikalwa nge-hertz.

Amasistimu e-Acousto Magnetic asebenza ku-58 KHz, okusho ukuthi isignali ithunyelwa ngokushaya noma ukuqhuma phakathi kuka-50 no-90 izikhathi ngesekhondi kuyilapho i-Radio Frequency noma i-RF isebenza ku-8.2 MHz.

Uhlobo ngalunye lwe-EAS lunezinzuzo, okwenza amanye amasistimu afaneleke kakhulu kubathengisi abathile kunamanye.

I-EAS iyindlela ephumelela kakhulu yokuvikela okuthengiswayo ekuntshontshweni.Isihluthulelo sokukhetha isistimu elungile yesitolo sakho sokuthengisa sihlanganisa ukucabangela uhlobo lwezinto ezithengiswayo, inani lazo, ukwakheka kwendawo yokungena nokunye okucatshangelwayo okufana nanoma yikuphi ukuthuthukiswa kwesikhathi esizayo ku-RFID.
