2D code recognition module kuti mupititse patsogolo luntha, kuti chidziwitso chazidziwitso chazidziwitso chazidziwitso chazidziwitso chazidziwitso chazidziwitso chazidziwitso chazida zotsanzika sichikuyenda bwino.

Ukadaulo wa barcode monga gawo lofunikira laukadaulo wazidziwitso, makamaka kugwiritsa ntchito kwambiri ukadaulo wozindikiritsa ma code 2d kwabweretsa kusintha kwanzeru komanso chidziwitso ndikukweza m'mafakitale ambiri. The self-service terminal recognition device scan code ndi imodzi mwazinthu zomwe zimayendetsedwa ndiyomangidwa mu 2d code recognition modulendi luso lozindikiritsa barcode mankhwala, amene mosavuta kupereka 2d code basi chizindikiritso ndi deta kufala thandizo kwa materminal anzeru.

Kugwiritsa ntchito 2dbarcode scanningmodule tsopano ndi yochuluka kwambiri, yomwe ingagwiritsidwe ntchito m'mafakitale ambiri. Mwachitsanzo, ndizosavuta kupeza pafupi nafe kuti makina opangira makina opangira makina opangira makina, makina odzipangira okha ntchito, malo opangira matikiti odzichitira okha, poyimitsa magalimoto odzilipira okha, makina amasewera, ndi makina otsegulira tchanelo. zonse zophatikizidwa ndi 2d code recognition module kudzera pa serial port kuti mupititse patsogolo luntha. Ogwiritsa ntchito amatha kuzindikira ndikuwerenga khodi ya 2d ya foni yam'manja (kuphatikiza nambala yolipira) pafupi ndi zenera loyang'ana, ngakhale m'malo amdima a foni yam'manja.
