Ntau hom QR Code thiab lawv cov ntawv thov

2D Code, tseem hu ua ob-dimensional barcode, yog ib txoj hauv kev tshiab ntawm kev encoding thiab khaws cov ntaub ntawv cov ntaub ntawv tsim los ntawm ib-seem barcode. QR cov lej tuaj yeem sawv cev rau ntau yam ntaub ntawv xws li cov cim Suav, duab, ntiv tes thiab suab. Vim nws lub tshuab muaj zog nyeem tau yooj yim, luam theej duab thiab siv tau yooj yim, thiab cov ntaub ntawv khaws cia ntau dua, QR cov lej tau siv dav hauv kev xa khoom thauj khoom, khw muag khoom, kev pabcuam kev lag luam, kev saib xyuas tshuaj, tshuaj lom neeg cov ntaub ntawv khaws cia, ID pov thawj, cov ntawv sau npe, kev thauj mus los ntse, yog dav siv nyob rau hauv kev ruaj ntseg.

Ob-dimensional codes tau muab faib ua hom stacked thiab matrix hom raws li cov txheej txheem coding sib txawv. Cov lej ob-dimensional feem ntau suav nrog QR code, PDF417, DM code, thiab lwm yam. Cov lej sib txawv yog siv rau hauv cov xwm txheej sib txawv raws li lawv cov yam ntxwv sib txawv.

QR code
QR code yog matrix ob-dimensional code nrog ultra-high-speed, tag nrho cov kev nyeem ntawv tus yam ntxwv, thiab yog tam sim no siv dav tshaj plaws. Nws feem ntau yog siv rau logistics thiab industrial automation ntau lawm tswj. Hauv lub neej txhua hnub, QR cov lej kuj tseem siv rau cov npav npav thiab tsheb npav caij npav thiab WeChat QR code daim npav lag luam.

 

PDF 417

 

PDF 417
PDF417 yog pawg QR code, uas yog cov ntaub ntawv nqa tau yooj yim nrog cov ntaub ntawv ceev thiab cov ntsiab lus siab, thiab cov ntaub ntawv khaws cia tsis tuaj yeem sau rov qab. Vim muaj cov ntaub ntawv loj loj thiab muaj kev ruaj ntseg tsis pub lwm tus paub thiab tiv thaiv cov khoom pov thawj ntawm ob txoj cai no, feem ntau yog siv rau hauv daim ntawv hla tebchaws, ntawv hla tebchaws thiab lwm yam ntaub ntawv.

 

DM Kev Pabcuam Kev Noj Qab Haus Huv

 

DM code
DM code yog matrix ob-dimensional code, uas tsuas yog siv lub perimeter rau kev txheeb xyuas thiab muaj kev ruaj ntseg siab, yog li nws yog feem ntau siv nyob rau hauv lub teb chaws tiv thaiv thiab kev ruaj ntseg, aerospace qhov chaw cim, thiab lwm yam.

 

Raws li QR code daim ntawv thov tau dhau los ua neeg nyiam, cov tshuab luam ntawv thiab QR code scanners rau luam ntawv QR cov lej kuj tseem yog qhov tseem ceeb.
