Ikhowudi ye-QR, igama elipheleleyo leKhowudi yokuPhendula eKhawulezayo, ekwabizwa ngokuba yi "Quick Response Code", yikhowudi ye-matrix enamacala amabini, eyaphuhliswa yinkampani yeemoto yaseJapan iDenso Wave ngo-1994, kunye nomqambi ophambili wekhowudi ye-QR uYuan Changhong. Kwakhona ke eyaziwa ngokuba "nguBawo weKhowudi yeQR".

 

Njengoko kunokubonwa kwigama, le khowudi inamacala amabini inokufundwa ngokukhawuleza kwaye iqatshelwe, kwaye ineempawu zokufunda ezikhawulezayo kakhulu kunye nezijikelezileyo. Le yibhakhowudi ye-optical efundeka ngomatshini ekwaziyo ukuqulatha ubutyebi bolwazi malunga nento encanyathiselwe kuyo. Ngenxa yomthamo omkhulu wedatha kunye nokulula kokufunda, iikhowudi ze-QR ngoku zisetyenziswa ngokubanzi kwilizwe lam.

 

Izinto eziluncedo kwiikhowudi zeQR

 

1: Isixa esikhulu sokugcinwa kolwazi

 Iikhowudi zebhakhowudi zesiNtu zinokuphatha malunga namasuntswana angama-20 olwazi, ngelixa iikhowudi zeQR zinokuphatha amashumi ukuya kumakhulu amaxesha olwazi oluninzi njengeebhakhowudi. Ukongeza, iikhowudi ze-QR zinokuxhasa iintlobo ezininzi zedatha (njengamanani, iileta zesiNgesi, iileta zesiJapan, iimpawu zesiTshayina, iimpawu, ibhinari, iikhowudi zokulawula, njl. njl.).

 

2: Unyawo oluncinci lokusetyenzwa kwedatha

 Ekubeni ikhowudi ye-QR inokucubungula idatha kwiindlela ezithe nkqo kunye nezithe tyaba zebhakhowudi ngexesha elifanayo, indawo ehlala kuyo ikhowudi ye-QR kuphela malunga nesinye seshumi sebhakhowudi yolwazi olufanayo.

 

3: Ikhono elinamandla lokuchasa intlonti

 Iikhowudi ze-QR zinamandla "umsebenzi wokulungisa impazamo". Kwiimeko ezininzi, nokuba ezinye iileyibhile zebhakhowudi zingcolisekile okanye zonakele, idatha inokufunyanwa kwakhona ngolungiso lwempazamo.

 

4: Ukufunda kunye nokuqatshelwa

 Iikhowudi ze-QR zinokufundwa ngokukhawuleza kulo naliphi na icala ukusuka kwi-360 °. Isitshixo ekufezekiseni le nzuzo silele kwiipateni ezintathu zokubeka kwikhowudi ye-QR. La manqaku okumisa anokunceda iskena sisuse ukuphazamiseka kwendlela yangasemva xa uskena ibhakhowudi kwaye ufezekise ukufunda ngokukhawuleza nangokuzinzileyo.

 

I-5: Umsebenzi wokudibanisa idatha yenkxaso

 Ikhowudi ye-QR inokwahlula idatha kwiikhowudi ezininzi, ukuya kuthi ga kwi-16 iikhowudi ze-QR zinokwahlulwa, kwaye iikhowudi ezininzi ezahluliweyo zinokudibaniswa kwikhowudi enye ye-QR. Eli nqaku livumela iikhowudi zeQR ukuba ziprintwe kwiindawo ezimxinwa ngaphandle kokuchaphazela ulwazi olugciniweyo.

 

                               

Isicelo somshicileli wekhowudi ye-QR

 

Iikhowudi ze-QR okwangoku zisetyenziswa ngokubanzi kulawulo lwezothutho, ulawulo logcino, ukulandeleka kwempahla, intlawulo yeselula kunye nezinye iinkalo. Iikhowudi ze-QR zikwasetyenziswa kubomi bemihla ngemihla kwiikhowudi zokukhwela ibhasi kunye ne-subway kunye namakhadi oshishino ekhowudi ye-WeChat QR.

 

Ngokwanda kokuthandwa kweekhowudi ze-QR, abashicileli bokushicilela iileyibhile zekhowudi ye-QR baye bayimfuneko. Okwangoku, iileyibhile zebarcode abashicileli kwimarike baxhasa ngokubanzi ushicilelo lweekhowudi zeQR.
