Iikhowudi zebar zaqalwa ngo-1952 e-United States ukukwazi ukufumanisa iimoto zikaloliwe zisebenzisa i-automated system, kodwa bekungekho ngo-1966 apho ikhowudi ye-bar yaqala ukusetyenziswa kwezorhwebo, isanda kwilizwe jikelele ngo-1980. imveliso.
Njengokuba iminyaka ihambile, iibhakhowudi ziyaqhubeka ukuba sisixhobo esisisiseko kwishishini, kodwa khange bakwazi ukuziqhelanisa ne-Intanethi kunye netekhnoloji entsha. Iikhowudi ze-QR zinokuqwalaselwa uguquko olusengqiqweni lweebhakhowudi, kodwa emva kokuhlala iminyaka eliqela kwintengiso, sibonile ukuba okwangoku akukabi njalo.
Ikhowudi ye-QR yibhakhowudi yebhakhowudi enamacala amabini ivumela ukuba sigcine idatha ebhaliweyo kwaye uninzi lwamaxesha basinika ikhonkco kwiphepha lewebhu, nangona inokusetyenziselwa olunye usetyenziso, le yeyona nto iphambili okoko yafika emarikeni.
Ikhowudi yeQR yenziwa liqela leToyota ngo-1994, kodwa kwade kwaphakathi kunyaka ka-2000 apho esi sixhobo singazange sithandwa luluntu jikelele. Le khowudi yeQR ihlala ibonwa rhoqo kwizibhengezo, kuba isithumela ngqo kwiwebhusayithi yomthengisi ngaphandle kokuyichwetheza kwisikhangeli.
Ngokungafaniyo neebakhowudi, Ukudala iikhowudi ze-QR yinkqubo elula kakhulu kwaye nawuphi na umsebenzisi angayenza. Ukuba ufuna ukwazi ukuba uyenza njani ikhowudi ye-QR ngedilesi yewebhu, siya kukubonisa ukuba yeyiphi inkqubo ekufuneka uyilandele, inkqubo eya kukumangalisa ngenxa yendlela elula ngayo.
Umthamo wokugcina weekhowudi zeQR
Ngelixa kuyinyani ukuba iikhowudi ze-QR (Ukuphendula ngokukhawuleza isiNgesi kuthetha ukuphendula ngokukhawuleza) zisetyenziselwa ukubandakanya iidilesi zewebhu, zihlala zisetyenziswa kwimizi-mveliso emikhulu apho ukufundwa kweekhowudi kufuneka kukhawuleze ngokwaneleyo ukuze kungalibazisi imveliso okanye ukuhanjiswa.
Olu hlobo lweekhowudi zinokuba namanani kuphela, iileta kunye neenombolo, ikhowudi yokubini kunye neKinja. Kuxhomekeke kubalinganiswa esibasebenzisayo, iikhowudi zeQR zinokugcina elona nani liphezulu labalinganiswa:
- Abalinganiswa bamanani kuphela: ubuninzi be-7089.
- Iileta kunye neenombolo: 4296 ubuninzi boonobumba.
- I-Binary: i-2953 byte
- I-Kana (abalinganiswa baseJapan): abalinganiswa abali-1817.
Uyenza njani iikhowudi zeQR
Indlela endiphawule ngayo ngasentla yenza ikhowudi yeQR yinkqubo elula kakhulu ukuba sinezixhobo ezifanelekileyo, kule meko i-Intanethi. Kwi-Intanethi, sinakho inani elikhulu lamaphepha ewebhu asivumelayo ukuba senze olu hlobo lwekhowudi kwidilesi yewebhu.
Ikhowudi yekhowudi yeQR
Ikhowudi yekhowudi yeQR Yenye yezo zisinika ezinye iinketho xa kuziwa ekuveliseni iikhowudi ze-QR ngephepha lewebhu kuba ayisivumeli kuphela ukuba sizenze kodwa ikwasivumela setha ubungakanani bekhowudi, kunye nokudityaniswa kwakhona.
Kuxhomekeke kwindawo esiza kuyibeka kuyo ikhowudi ye-QR, ubungakanani bokugqibela bekhowudi evelisiweyo kubaluleke kakhulu, kuba ukuba sizama ukuyikhulisa ngokusebenzisa isicelo ukuyibeka kwipowusta, oku inokuba ipikseli kwaye ayihambelani nabafundi bekhowudi yeQR.
Enye into ekufuneka uyiqwalasele xa usenza ikhowudi ye-QR, kwaye eli phepha lisinika ukungafuneki kwakhona. Ukufunwa kwakhona ngumsebenzi ivumela ikhowudi ukuba ifundwe nokuba inxenye yayo yonakele. Ukuphakama kwenqanaba lokuphindaphindeka emsebenzini, kokukhona ikhowudi iya kuthi isinike ukuba ifundwe ukuba yonakele. Olu phawu kufuneka luthathelwe ingqalelo ukuba sifuna indawo ekuyo ikhowudi ye-QR yindawo enokuthi ichaphazeleke nakuphi na ukunxibelelana nezinye izinto okanye ezivezwe yimozulu embi.
