Nthawi zambiri anthu sindikudziwa momwe kuwerenga barcode pa zinthu zimene kugula m'masitolo, ndipo mfundo zimenezi lodabwitsa mikwingwirima wakuda ndi danga woyera angatiuze osati za dziko chiyambi, komanso ena a magawo zofunika za ulimi.

Zizindikiro za munthu uyu akuti amadziwa yekha ziwerengero ataima pa chiopsezo. Kodi dziko bala ovomerezeka? Mawu amenewa amanena wapadera likutipatsa chifaniziro cha mfundo yadigito. Ndi mndandanda wa zitsulo ndi malo amene anapangidwa kuti kuwerenga zipangizo ziwalo. Pa nthawi yomweyo mu dziko chiyambi amasonyeza woyamba manambala awiri kapena atatu.

Dziwani kuti barcode anatulukira ndipo okhala mu 1949, Woodland ndi Silver. Kutulukira pano analola kuti kuyankha ndi kulamulira zinthu zolondola zikutanthauza pa njira yawo kuchokera Mlengi ogula.

Pakali pano, nthawi zambiri ntchito American Universal chofunika kachidindo kapena dongosolo European 'kala' ikusonyeza. Wotchuka kwambiri ndi 13 manambala code, umene umayamba mu Europe mu 1977.

Pa nthawi yomweyo pa mabuku kungakhale barcode za dziko ndi manambala oyambirira otchedwa ndi mankhwala ena anyamula osakaniza mitundu iwiri ya wolemba pulogalamu ntchito zitsulo ndi malo a osiyanasiyana makulidwe.

Ogula nthawi zonse chidwi ndi Mlengi mankhwala. Kudziwa dziko ndi bala malamulo ndi losavuta mokwanira. Kokwanira kuti ndidziwe chiwerengero omwe akusonyeza chiyambi cha katundu.

M'mayiko Mabakodi ndi yosiyanasiyana. Choncho, pa ma CD a mankhwala kuchokera United States ndi Canada ndi manambala choyamba 00-09, wa Germany - 400-440, Poland - 590, China - 690, ndi Russia - 460-469.

Iwo amalankhula za kampani, amene manufactures mankhwala. Bar malamulo anatchulapo magawo munthu wa mankhwala - dzina lake, makhalidwe ogula kukula ndi kulemera, zosakaniza ndi mitundu. Palinso cheke manambala. Ali kutsimikizira kulondola wa Werengani wolemba pulogalamu ntchito Zitsulo zofufuzira zidazo wapadera. Nthawi zina angathe kuperekedwa kwa fanizo lina, zimene zikusonyeza mankhwala pansi kupanga chilolezo.

Barcoding n'kofunika kwambiri. Izo zikhale zosavuta kusunga mbiri katundu kudzera zopezera makompyuta kudziwa kuchuluka kwa awo kukhazikitsa tsiku, komanso kuteteza kuchotsa katundu akadali yosalipidwa masitolo kunja ndi kumasitolo aakuluakulu.
