Umshicileli weBhakhowudi
Ibhakhowudi, ekwaziwa ngokuba yibhakhowudi, sisichongi esingumzobo. Lungiselela imivalo emnyama emininzi kunye nezikhenkce zobubanzi obuhlukeneyo ngokwemigaqo ethile yekhowudi yokuvakalisa ulwazi. Iikhowudi zebhakhowudi ziquka iibhakhowudi ezinomlinganiselo omnye kunye neekhowudi ezimacala mabini.
Ukuza kuthi ga ngoku, kukho iintlobo ezininzi zebhakhowudi ezinomlinganiselo omnye, njengekhowudi ye-UPC kunye nekhowudi ye-ENA, ezizezona zixhaphakileyo kwiibhakhowudi zentengiso ebomini, iKhowudi 39 esetyenziswa ikakhulu kushishino lweemoto kunye nolawulo lwencwadi, kunye neKhowudi 128, enokuthi isetyenziswe njengekhowudi yokuchonga isikhongozeli kwishishini lezothutho. Kunye ne-International Standard Book Number ISBN njalo njalo. Nangona kunjalo, ekubeni ezi barcode zinomlinganiselo omnye, ulwazi lurekhodwa kuphela kwicala elithe tye, kwaye ukuphakama kwebhakhowudi akugcini ulwazi. Ngoko ke, umthamo wokugcina ulwazi lweekhowudi ezinomlinganiselo omnye ulinganiselwe.
Iikhowudi ezimbini-dimensional ziquka umqolo-uhlobo lwebhakhowudi ezimbini-dimensional kunye ne-matrix-dimensional barcodes. Xa kuthelekiswa neekhowudi ze-1D, iibhakhowudi ze-2D zinomthamo omkhulu wokugcina idatha, inyawo encinci kunye nokuthembeka okunamandla. Okwangoku, ukusetyenziswa kwekhowudi ye-two-dimensional kuninzi kwaye kubanzi. Iikhowudi ze-QR ezisetyenziswa ngokuqhelekileyo ziikhowudi ze-QR zokuthenga ithikithi lombane, iikhowudi zokuhlawula, amatikiti emuvi ye-elektroniki, amakhadi oshishino, ukuthengisa, ukuthengisa, ukuzonwabisa, iikhowudi ze-DM zebhanki yezemali, iileyibhile zoshishino, kunye ne-PDF417 yokupasa kunye nelotho. .
