Isingeniso

Ikhodi ye-QR isiyingxenye ebalulekile yokuphila kwethu kwansuku zonke. Udinga ukuskena ikhodi ye-QR lapho ungena ngemvume, lapho ukhokhela izinto, nalapho ungena ngemvume ukuze uthole imihlangano. Uyini umgomo osekela ubuchwepheshe obunjalo bekhodi ye-QR esetshenziswa kabanzi? Leli phepha lizohlaziya izimiso zobuchwepheshe zekhodi ye-QR ngokusekelwe ekuthuthukisweni kwayo kanye nezimo ezivamile zohlelo lokusebenza.

Umlando omfushane wokuthuthukiswa kwekhodi ye-QR

2.1 ukuzalwa kwekhodi yebha

Ngaphambi kokuthi siqonde isimiso se-two-dimensional ubuchwepheshe bekhodi, ake sibheke kafushane ukuthi buthuthuke kanjani. Kusukela ngo-1948, uBernard salvo wayengumfundi oneziqu e-Philadelphia Institute of gas technology. Ngenhlanhla, wathola ukuthi umnikazi wesitolo esikhulu sendawo wayefuna umphathi wesitolo asize ukuklama idivayisi ekwazi ukuskena izintengo zempahla ukuze kuthuthukiswe ukusebenza kahle kokuthengiswa kwempahla esitolo. Ngenxa yokuthi othatha imali esitolo esikhulu udinga ukungena esakhiweni mathupha ngaso sonke isikhathi lapho elungisa izimpahla, ukusebenza kahle kokukhokha kwe-cashier kuphansi kakhulu lapho ukugeleza kwabagibeli besikhathi esengeziwe kufinyelela. Kodwa uDini wacabanga ukuthi kwakuyinto enzima kakhulu ukuyenza.

Nokho, uBernard selver nomngane wakhe u-Joseph woodland bacabanga ukuthi kwakuyithuba elikhulu lebhizinisi futhi banquma ukuklama umkhiqizo okwazi ukuhwebelana. Ngemva kokuzama isikimu se-ultraviolet irradiation graphite luminescence, i-blind spot system kanye nesistimu yezimpawu zamachashazi, azizange zisetshenziswe kakhulu ngenxa yemikhawulo yezobuchwepheshe ngaleso sikhathi.

Ngokucwayiza kweso, ngawo-1960, i-woodland ayizange phakamisa umbono wegolide ongazange ufeze ukusetshenziswa kwezentengiselwano kuleyo minyaka. Ngalesi sikhathi, wayesevele engunjiniyela we-IBM. Ngesikhathi ehlala enkampanini, wayehlale echaza imibono yakhe mayelana nokusetshenziswa kobuchwepheshe bekhodi yebha, futhi ozakwabo babehlale begcizelela ukubaluleka kokuhweba kwekhodi yebha. Ngesikhathi esifanayo, ama-lasers namakhompyutha asetshenzisiwe, futhi isisekelo sobuchwepheshe sokusetshenziswa kwekhodi yebha sesiqediwe. Cishe ngo-1969, i-Woodland yabamba iqhaza esikeneni sesitolo esikhulu kanye nethimba lephrojekthi yokucwaninga ilebula eyatshalwa yi-IBM, eyayiholwa nguGeorge laurel. Ngemva kweminyaka eminingana yocwaningo olunzima, i-IBM yagcina yethula ibhakhodi elamukelekayo.

Ngomhla zingama-26 kuNhlangulana, 1974, isithwebuli sebhakhodi sokuqala emhlabeni safakwa esitolo esikhulu esinamatshe e-Troy, e-Ohio. Into yokuqala eskeniwe bekungamaphekhi angu-10 esithelo esinoshukela sika-Wrigley, esiqoqwe yi-American Museum of History. Khona-ke, ibhakhodi isetshenziswa kakhulu ezimpahleni, ezincwadini, eposini nakwezinye izinhlelo, okuthuthukisa kakhulu ukusebenza kahle kwebhizinisi.
