Khodi ya QR, dzina lathunthu la Quick Response Code, yomwe imadziwikanso kuti "Quick Response Code", ndi code ya matrix yokhala ndi mbali ziwiri, yomwe idapangidwa ndi kampani yamagalimoto yaku Japan ya Denso Wave mu 1994, komanso woyambitsa wamkulu wa QR code Yuan Changhong. Komanso amadziwika kuti "Bambo wa QR Code".

 

Monga momwe zikuwonekera kuchokera ku dzinali, kachidindo kakang'ono kawiri kameneka kakhoza kuwerengedwa ndi kuzindikiridwa mwamsanga, ndipo imakhala ndi machitidwe owerengera othamanga kwambiri komanso ozungulira. Iyi ndi barcode yowerengeka ndi makina yomwe imatha kukhala ndi zidziwitso zambiri za chinthu chomwe chalumikizidwa. Chifukwa cha kuchuluka kwa data komanso kusavuta kuwerenga, ma QR code amagwiritsidwa ntchito kwambiri mdziko langa.

 

Ubwino wamakhodi a QR

 

1: Kuchuluka kwazinthu zosungirako zambiri

 Ma barcode akale amatha kudziwa zambiri zama bits 20, pomwe ma QR amatha kudziwa zambiri kuchulukitsa kambirimbiri kuposa ma barcode. Kuphatikiza apo, manambala a QR amatha kuthandizira mitundu yambiri ya data (monga manambala, zilembo za Chingerezi, zilembo za Chijapanizi, zilembo zaku China, zizindikilo, binary, zowongolera, ndi zina).

 

2: Njira yaying'ono yosinthira deta

 Popeza nambala ya QR imatha kukonza deta munjira yoyimirira komanso yopingasa ya barcode nthawi imodzi, malo omwe ma QR code amakhala pafupifupi gawo limodzi mwa magawo khumi a barcode pazambiri zomwezo.

 

3: Kutha kwamphamvu koletsa kuyipitsa

 Makhodi a QR ali ndi "ntchito yokonza zolakwika" yamphamvu. Nthawi zambiri, ngakhale zilembo zina za barcode zili zoipitsidwa kapena kuonongeka, detayo imatha kubwezeredwa pokonza zolakwika.

 

4: Kuwerenga kozungulira ndi kuzindikira

 Ma QR code amatha kuwerengedwa mwachangu mbali iliyonse kuchokera ku 360 °. Chinsinsi chokwaniritsira izi chagona pamitu itatu yoyikira mu QR code. Zizindikiro zoyikira izi zitha kuthandiza scanner kuthetsa kusokoneza kwapambuyo yakumbuyo ikasanthula barcode ndikuwerenga mwachangu komanso mokhazikika.

 

5: Thandizo lophatikizana la data

 Khodi ya QR imatha kugawa zidziwitso m'makhodi angapo, mpaka ma 16 a QR amatha kugawidwa, ndipo ma code angapo ogawidwa amatha kuphatikizidwa kukhala nambala imodzi ya QR. Izi zimathandiza kuti ma code a QR asindikizidwe m'malo opapatiza popanda kusokoneza zomwe zasungidwa.

 

                               

Pulogalamu yosindikiza ya QR code

 

Ma code a QR pakadali pano amagwiritsidwa ntchito kwambiri pakuwongolera zinthu, kasamalidwe ka malo osungiramo zinthu, kutsata zinthu, kulipira mafoni ndi magawo ena. Makhodi a QR amagwiritsidwanso ntchito pamoyo watsiku ndi tsiku pamabasi ndi ma mayendedwe apansi panthaka komanso makhadi abizinesi a WeChat QR.

 

Chifukwa chakuchulukirachulukira kwa ma code a QR, osindikiza osindikiza zilembo za QR akhala ofunikira. Pakadali pano, osindikiza a barcode pamsika nthawi zambiri amathandizira kusindikiza ma QR code.
