Kev xaiv cov qhab nia barcode rau kev tsim khoom

Kev lag luam ib puag ncig yog tshwj xeeb, thiab feem ntau muaj qhov siab xav tau ntawm kev daws teeb meem thiab kev nyeem ntawv tus lej ntsuas ntawm barcode scanner. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau muaj qib siab dua ntawm kev tswj hwm plua plav, tiv thaiv kev nyab xeeb, tiv thaiv kev poob thiab tawm tsam. Ambient kub ntau yog loj. Kev siv lub tshuab ntsuas barcode yog kom sau cov ntaub ntawv cov ntsiab lus muaj nyob hauv barcode thaum lub sijhawm ua haujlwm ntau lawm rau kev txheeb suav cov ntaub ntawv thiab kev ua cov khoom. Kev tsim khoom tau muab faib rau kev lag luam hnyav thiab lub teeb pom kev lag luam, kev tsim khoom tsis zoo thiab kev tsim khoom txuas ntxiv. Kev cob qhia ua haujlwm thiab txheej txheem tsim khoom muaj lawv tus kheej cov yam ntxwv. Cov neeg tsim khoom lag luam yuav tsum xaiv lub tshuab ntsuas barcode lossis cov ntawv sau cov ntaub ntawv raws li lawv tus kheej.
