What Is a 2D barcode and How Does It Work?

2D (ob-dimensional) barcode yog cov duab nraaj uas khaws cov ntaub ntawv kab rov tav raws li ib-dimensional barcodes ua, nrog rau vertically.Yog li ntawd, lub peev xwm cia rau 2D barcodes ntau dua 1D cov lej.Ib qho 2D barcode tuaj yeem khaws txog 7,089 tus cim tsis yog 20 tus cim muaj peev xwm ntawm 1D barcode.Cov lus teb ceev ceev (QR) cov lej, uas ua kom cov ntaub ntawv nkag tau sai, yog hom 2D barcode.
Android thiab iOS smartphones siv 2D barcodes nyob rau hauv lawv built-in barcode scanners.Tus neeg siv yees duab 2D barcode nrog lawv lub koob yees duab smartphone, thiab tus nyeem ntawv built-in txhais qhov URL encoded, coj tus neeg siv ncaj qha mus rau lub vev xaib cuam tshuam.
Ib qho 2D barcode tuaj yeem tuav cov ntaub ntawv tseem ceeb hauv qhov chaw me me.Cov ntaub ntawv no tau nthuav tawm rau tus neeg muag khoom, tus neeg muag khoom lossis cov neeg siv khoom thaum cov cai raug tshuaj xyuas los ntawm 2D imaging scanners lossis lub zeem muag.
Cov ntaub ntawv yuav suav nrog: Lub npe tsim khoom, Batch / ntau tus lej, Cov khoom hnyav, Siv los ntawm / zoo tshaj plaws ua ntej hnub, Tus Neeg Loj Hlob ID, GTIN tus lej, Tus lej xov tooj, Tus nqi

Hom 2D barcodes

Muaj cov hom tseem ceeb ntawm2D barcode scannercim: GS1 DataMatrix, QR code, PDF417
GS1 DataMatrix yog hom 2D barcode ntau tshaj plaws.Woolworths tam sim no siv GS1 DataMatrix rau nws 2D barcodes.
GS1 Datamatrix 2D barcodes yog cov cim me me ua los ntawm cov square modules.Lawv nyiam kos cov khoom me me xws li cov khoom tshiab.

1.Breaking down GS1 DataMatrix

1.Separate qhov chaw: tus qauv finder siv los ntawm lub scanner los nrhiav lub cim, thiab cov ntaub ntawv encoded
2.Txawm cov kab thiab kab
3.Ib lub teeb 'square' nyob rau sab xis sab xis
4.Can encode cov ntaub ntawv ntev kuj sib txawv - lub cim loj txawv raws li tus nqi ntawm cov ntaub ntawv encoded
5.Can encode mus txog 2335 alphanumeric cim lossis 3116 tus lej (hauv squareform)

2.QR codes

QR cov lej feem ntau yog siv los txuas rau qhov chaw URL thiab tam sim no tsis siv rau kev muag khoom.Lawv feem ntau siv rau cov neeg siv khoom ntim khoom, vim tias lawv tuaj yeem nyeem tau los ntawm lub koob yees duab smartphone.
Siv GS1 Cov Txuas Txuas, QR cov lej tuaj yeem ua haujlwm raws li kev siv ntau qhov barcodes uas tso cai rau ob qho tib si kev koom tes ntawm cov neeg siv khoom thiab kev saib xyuas tus nqi, tshem tawm qhov xav tau rau ntau tus lej noj qhov chaw ntim khoom muaj txiaj ntsig.

3. PAB 417

PDF417 yog 2D barcode uas tuaj yeem khaws ntau yam ntaub ntawv binary, suav nrog cov lej lej thiab cov cim tshwj xeeb.Nws tseem tuaj yeem khaws cov duab, kos npe thiab cov ntiv tes.Yog li ntawd, kev txheeb xyuas tus kheej, kev tswj cov khoom muag thiab cov kev pabcuam thauj mus los feem ntau siv lawv.PDF ib feem ntawm nws lub npe los ntawm lo lus "portable document file."Qhov "417" yog hais txog nws plaub kab thiab qhov chaw nyob hauv txhua tus qauv, muaj 17 cim.

Barcodes ua haujlwm li cas?

Hauv cov ntsiab lus, barcode yog ib txoj hauv kev los encode cov ntaub ntawv mus rau hauv cov qauv pom (cov kab dub thiab qhov chaw dawb) uas lub tshuab (barcode scanner) tuaj yeem nyeem.
Kev sib xyaw ua ke ntawm cov kab dub thiab dawb (tseem hu ua cov ntsiab lus) sawv cev rau cov ntawv sib txawv uas ua raws li cov txheej txheem tsim ua ntej rau qhov barcode (ntxiv rau hom barcodes tom qab).Abarcode scanneryuav nyeem cov qauv no ntawm cov kab dub thiab dawb thiab txhais lawv mus rau hauv kab ntawm kev sim uas koj lub khw muag khoom ntawm qhov muag yuav nkag siab.
