Ikhadi leMagnetic Strip

Ikhadi lomgca wemagnethi likhadi eliphakathi lokurekhoda. Yenziwe ngeplastiki-yamandla aphezulu,{2}}ubushushu obuphezulu-iplastiki ekwaziyo ukumelana okanye iphepha{4}}iplastiki egqunywe, enokufuma{5}}nobungqina bokufuma, ukunxiba{6}}ukuxhathisa kwaye bhetyebhetye, kulula ukuyiphatha, kwaye izinzile kwaye ithembekile ukuyisebenzisa. Ngokuqhelekileyo, elinye icala lekhadi lamagnetic liprintwa ngolwazi oluchazayo, njengolwalathiso lokufaka ikhadi; elinye icala linomaleko wemagnethi okanye umgca wemagnethi, one-2{10}}iingoma ezi-3 ukurekhoda idatha yolwazi olufanelekileyo. Iingoma ezimbini zokuqala zifundwa{11}}kuphela iingoma, kwaye eyesithathu yingoma efundwayo, efana nokurekhoda iibhalansi zencwadi.

Ulwazi lokufunda kunye nokubhalwa kwamakhadi omgca wemagnethi kulula, kulula ukuyisebenzisa, kwaye iphantsi kweendleko, ngoko iye yaphuhliswa kwangaphambili kwaye ingene kwiindawo ezininzi zesicelo, ezifana namakhadi eefowuni ezihlawulwa kwangaphambili, amakhadi entlawulo, amakhadi okuqeshwa, amatikiti, amakhadi okugcina, ikhadi letyala, njl. Ngokomzekelo, xa sicinga ngeUnited States, abantu abangaphezu kwezigidi ezingama-200 banamakhadi okuthenga ngetyala aliwaka lesigidi sezigidi, abanamakhadi abali-110 lezigidi, aba-5 ngomntu ngamnye, yaye batya imali emalunga nama-469,5 eebhiliyoni zeerandi. Phakathi kwazo, amakhadi okuthenga ngetyala ambalwa enziwe ngamakhadi emagnethi, avelise izibonelelo ezicacileyo kwezoqoqosho nezentlalo.

Ukuhlela ikhadi lemagnethi
Uhlobo lomgca wemagnethi: i-anti {0}ikhadi lemagnetic jikelele (300oe)
Ikhadi lokumelana nemagnethi ephezulu (3500oe)
Uhlobo loshicilelo oluthe ngqo: ikhadi eliphantsi lokumelana nemagnethi (300oe) (elinje: amatikiti epaki)
Ikhadi eliphezulu lokuchasa-imagnetic card (2700oe) (elifana ne: ikhadi likaloliwe, ikhadi lefowuni)
Phawula:
Ukumelana nemagnethi: Isetyenziselwa ukulinganisa isakhono somcu wemagnethi ukuxhathisa ilahleko yedatha ebangelwa yimpembelelo yemagnethi yangaphandle, kunye nokuchasana nokumelana ne-demagnetization. Ukusabela kwemagneti. (Ukunyanzeliswa) iyunithi yi-OE (Oersted);
Umcu wemagnethi ophantsi we-antimagnetic: i-anti-yesiqhelo echasene ne-degaussing strip magnetic, ipropathi yemagnethi iqhele ukuba yi-300~650 (OE);
Umcu ophakamileyo wemagnetic wediamagnetic: unomcu wemagnetic wediamagnetic ophezulu, ukuxhathisa kwemagnethi ngokuqhelekileyo ngama-2750 (OE), 3500 (OE) kunye ne-4000 (OE) imicu yemagnethi kunye neengoma zemagnethi.
Kukho iingoma ezi-3 kumcu wemagnethi. Ingoma yoku-1 kunye ne-2 ifundwa kuphela-iingoma kuphela, kwaye ulwazi olushicilelwe kwiingoma lunokufundwa kuphela kwaye aluvumelekanga ukuba lubhalwe okanye luguqulwe ngexesha lokusetyenziswa. Ingoma yesi-3 yincwadi efundwayo{7}} ebhaliweyo, enokufundwa okanye ibhalwe isetyenziswe.
Umkhondo we-1 unokurekhoda amanani (0-}9), oonobumba (AZ) kunye nezinye iisimboli (ezifana nezibiyeli, izahluli, njl.), kwaye unokurekhoda ukuya kumanani angama-79 okanye iileta.
Abalinganiswa abarekhodwe kumzila 2 no-3 banokuba ngamanani kuphela (0-9). Umkhondo we-2 unokurekhoda ukuya kuthi ga kwiimpawu ze-40, umkhondo wesi-3 unokurekhoda ukuya kuthi ga kwiimpawu ze-107. umfundi wekhadi magnetic
Ngokubanzi, amakhadi emagnethi asetyenziswa kwi{0}}imimandla engeyiyo eyemali, kwaye lulwazi kuphela olurekhodwa kwingoma yesibini. Amakhadi amagnetic asetyenziswa kwintsimi yezemali, kwaye iingoma zemagneti 1, 2, kunye ne-3 zinokusetyenziswa. Ngokomzekelo, i-ICBC isebenzisa i-magnetic tracks 1 kunye ne-3, kwaye i-CCB isebenzisa iingoma zemagneti 2 kunye ne-3.
Ukhuseleko kunye neengxaki ezikhoyo zekhadi lamagnetic A. Imfihlo kunye nokhuseleko lwekhadi zihluphekile
Ulwazi olukumgca wemagnethi kulula ukufundeka, kwaye kulula nokuguqula ngokungekho mthethweni umxholo kumgca wemagnethi, ngoko ke kumaxesha amaninzi ikhadi lemagnethi lisetyenziswa njengokufakwa kwedatha engatshintshiyo. Nangona ithrekhi yesithathu ifundeka kwaye ibhalwe kwaye inentsimi yesixa, isetyenziselwa kuphela izicelo ezinexabiso elincinci, njengamakhadi efowuni.
B. Inkqubo yesicelo esebenzisa amakhadi amagnetic idinga inkxaso yenkqubo yekhompyutheni ethembekileyo kunye nedatha ephakathi
Kwishishini lezemali, ikhadi lamagnetic elisetyenziswe njengekhadi lentengiselwano yezemali lisetyenziswa ngokubanzi kunye nenkqubo yenethiwekhi yekhompyutha enamandla kwaye ethembekileyo. Ulwazi olunjengemali kunye neerekhodi zentengiselwano zigcinwa kuvimba weenkcukacha wekhompyutha yeziko lezemali. Ikhadi eligcinwe ngumsebenzisi libonelela kuphela inombolo ye-akhawunti yomsebenzisi ephambili, njl.njl Ulwazi lwesalathisi sokufumana ngokukhawuleza idatha yomsebenzisi kwisiseko sedatha.

Iifayile ezishisayo: ikhadi lemagnethi, iTshayina, abavelisi, ababoneleli, umzi-mveliso, olungiselelweyo, ngexabiso eliphantsi, ixabiso eliphantsi, isampulu yasimahla
