2D code lees paub module los txhim kho kev txawj ntse, yog li kev pabcuam tus kheej lub davhlau ya nyob twg lees paub ntaus ntawv code farewell tsis muaj txiaj ntsig

Barcode thev naus laus zis ua ib feem tseem ceeb ntawm cov ntaub ntawv thev naus laus zis, tshwj xeeb tshaj yog kev siv dav dav ntawm 2d code paub txog tshuab tau coj cov kev txawj ntse thiab cov ntaub ntawv hloov pauv thiab kho dua tshiab rau ntau lub lag luam.Tus kheej-kev pabcuam davhlau ya nyob twg paub ntaus ntawv scan code yog ib qho ntawm cov ntawv thov nqa los ntawmbuilt-in 2d code paub modulethiab barcode paub cov khoom siv thev naus laus zis, uas tuaj yeem yooj yim muab 2d code tsis siv neeg txheeb xyuas thiab cov ntaub ntawv xa mus txhawb rau cov ntse terminals.

Kev siv ntawm 2dbarcode scanningmodule tam sim no dav heev, uas tuaj yeem siv rau ntau qhov kev lag luam.Piv txwv li, nws yog ib qho yooj yim mus nrhiav tau nyob ib ncig ntawm peb hais tias tus kheej-kev pab cuam vending tshuab charger, lub self-service ordering tshuab, tus kheej-kev pab cuam daim pib davhlau ya nyob twg, qhov chaw nres tsheb rau tus kheej them nqi davhlau ya nyob twg, lub tshuab ua si, thiab lub channel rooj vag tshuab. tag nrho kev koom ua ke nrog 2d code paub module los ntawm qhov chaw nres nkoj serial los txhim kho kev txawj ntse.Cov neeg siv tuaj yeem nkag siab sai thiab nyeem 2d code ntawm lub xov tooj ntawm tes (xws li cov lej them nyiaj) nyob ze ntawm lub qhov rais scanning, txawm nyob hauv qhov tsaus ntuj ntawm lub xov tooj ntawm tes.
