Dab tsi yog vim li cas vim li cas lub barcode scanner module tsis tuaj yeem paub txog barcodes?

Barcode scanner modules tau ua ib feem tseem ceeb ntawm kev lag luam muag khoom rau ntau xyoo lawm. Cov cuab yeej no tau pab ua kom cov txheej txheem kev lag luam smoother thiab sai dua. Txawm li cas los xij, qee zaus, bar code scan modules tsis paub txog qee qhov barcodes, ua rau tsis yooj yim rau cov neeg siv khoom thiab cov khw muag khoom. Hauv tsab xov xwm no, peb yuav tshawb txog cov laj thawj vim li cas tus nyeem ntawv barcode modules tsis paub txog barcodes thiab yuav ua li cas los daws cov teeb meem no.

Daim pib barcode scanner module	QR code scanner module

 

Ua ntej, cia peb saib ntawm qr code scanner module nws tus kheej. Muaj ntau qhov laj thawj vim li cas nws yuav tsis paub txog barcode. Ib qho ntawm cov laj thawj tseem ceeb yog outdated firmware. Firmware yog software uas tau muab tso rau hauv lub cuab yeej kho vajtse. Zoo li lwm yam software, firmware yuav tsum tau hloov kho tsis tu ncua. Yog hais tias lub firmware yog outdated, nws yuav tsis muaj peev xwm nyeem barcodes tshiab.

 

Lwm qhov laj thawj yog vim li cas lub barcode scanning module yuav tsis paub txog tus lej barcode yog vim muaj peev xwm qis barcode scanner. Yog tias lub scanner tsis zoo, nws yuav tsis tuaj yeem nyeem cov barcode. Qhov no tuaj yeem muaj tseeb ntawm ob qho tib si linear thiab 2D barcodes. Qee zaum, lub scanner tsuas yog qias neeg thiab yuav tsum tau ntxuav. Lwm qhov ua tau yog siv lub tshuab luam ntawv uas tsuas tuaj yeem nyeem ib-seem barcodes nyeem ob-dimensional barcodes.

 

Tam sim no, cia peb saib cov barcodes lawv tus kheej. Zoo li nyob rau hauv cov ntaub ntawv ntawm qr code nyeem ntawv module, muaj ntau yam laj thawj vim li cas barcodes yuav tsis lees paub. Ib qho laj thawj yog kev puas tsuaj rau lub barcode. Yog hais tias tus barcode raug khawb, torn, los yog lwm yam puas, nws yuav tsis nyeem tau los ntawm lub scanner. Ib yam li ntawd, yog tias tus barcode luam tawm tsis zoo lossis siv cov ntaub ntawv tsis zoo, lub scanner yuav tsis tuaj yeem nyeem nws.

 

Lwm qhov laj thawj vim li cas barcodes yuav tsis lees paub yog vim qhov sib piv ntawm barcode. Qhov sib piv piv yog qhov sib txawv ntawm lub teeb thiab tsaus qhov chaw ntawm barcode. Yog tias qhov sib piv ntawm qhov sib piv tsawg dhau, lub cuab yeej yuav tsis tuaj yeem paub qhov txawv ntawm cov kab thiab qhov chaw ntawm barcode. Qhov no tuaj yeem tshwm sim yog tias qhov barcode luam tawm hauv greyscale es tsis txhob xim dub thiab dawb lossis yog tias nws luam tawm ntawm cov khoom uas pom lub teeb ntau dhau.

 

Txhawm rau daws cov teeb meem no, muaj ob peb kauj ruam yooj yim uas tuaj yeem ua tau. Ua ntej, xyuas kom meej tias tus nyeem ntawv barcode module tau hloov kho nrog cov firmware tshiab. Qhov no yuav ua kom paub tseeb tias nws tuaj yeem paub qhov tseeb barcodes. Qhov thib ob, yog tias lub scanner tsis zoo, nws yuav tsum tau hloov. Thib peb, yog tias barcode puas lossis luam tawm tsis zoo, yuav tsum tau luam tawm barcode tshiab. Thaum kawg, yog tias qhov sib piv ntawm barcode tsawg dhau, nws yuav tsim nyog los luam cov ntawv barcode rau ntawm cov khoom uas nqus tau ntau lub teeb.

 

Hauv kev xaus, bar code scaner modules yog cov cuab yeej tseem ceeb hauv kev lag luam muag khoom. Tsuas yog ua siab ntev nrhiav qhov laj thawj ib kauj ruam peb tuaj yeem nrhiav kev daws teeb meem thiab siv cov cuab yeej tsim nyog tshaj plaws.
