Kunyangwe muverengi wega wega achiverenga mabarcode nenzira dzakasiyana, mhedzisiro ndeye kushandura ruzivo kuita masaini edhijitari uyezve mu data rinogona kuverengwa kana kuenderana nemakomputa.Iyo decoding software mune imwe mudziyo inopedzwa, iyo barcode inocherechedzwa uye inosiyaniswa neiyo decoder, yobva yaiswa pakombuta inotambira.

Kurodha dhata kunoda kubatanidzwa kana kusanganisirwa neanotambira, uye imwe neimwe interface inofanirwa kunge iine mativi maviri akasiyana: imwe ndeye yemuviri layer (hardware), uye imwe yacho inonzwisisika layer, iyo inoreva kutaurirana protocol.Yakajairika interface nzira ndeiyi: keyboard port, serial port kana yakananga kubatana.Paunenge uchishandisa iyo keyboard interface nzira, iyo data yebhakodhi zviratidzo inotumirwa nemuverengi inoonekwa nePC kana iyo terminal kuti ive iyo data inotumirwa neyayo keyboard, uye panguva imwe chete, makiyibhodhi avo anogonawo kuita mabasa ese.Kana uchishandisa iyo keyboard port yekubatanidza inononoka, kana dzimwe nzira dzekushandisa dzisipo, isu tichashandisa serial port yekubatanidza nzira.Pane zvirevo zviviri zvekubatana kwakananga pano.Imwe inoreva kuti muverengi anoburitsa zvakananga data kumugadziri asina yekuwedzera decoding midziyo, uye imwe inoreva kuti iyo decoded data yakabatana zvakananga kune mugamuchiri pasina kushandisa keyboard.Mamwe mazwi anowanzo shandiswa Dual Interface: Zvinoreva kuti muverengi anogona kubatanidza zvakananga zvishandiso zviviri zvakasiyana, uye otomatiki kugadzirisa uye kutaurirana nechero terminal, semuenzaniso: CCD inoshandiswa kubatanidza IBM's POS terminal masikati, uye husiku.Ichabatanidza kune inotakurika data terminal yezvigadzirwa zvekutengesa, uye shandisa yakavakirwa-mukati mbiri interface kugona kuita shanduko pakati pezvishandiso zviviri zviri nyore.Flash memory (Flash Memory): Flash memory ichip inogona kuchengetedza data isina magetsi, uye inogona kupedzisa kunyorazve data nekukasira.Zvizhinji zvezvigadzirwa zveWelch Allyn zvinoshandisa flash memory kutsiva maPROM ekutanga, zvichiita kuti chigadzirwa chiwedzere kukwidziridzwa.HHLC (Hand Held Laser Compatible): Mamwe materminal asina decoding midziyo anogona chete kushandisa kunze decoder kutaura.Iyo protocol yeiyi nzira yekutaurirana, inowanzozivikanwa selaser simulation, inoshandiswa kubatanidza CCD kana laser reader uye yekunze Seta decoder.RS-232 (Yakakurudzirwa Chiyero 232): TIA/EIA mwero wekufambiswa kwemashoko pakati pemakomputa nemaperipheral akadai semabhakodhi ekuverenga, Modem, uye mbeva.RS-232 inowanzoshandisa 25-pin plug DB-25 kana 9-pin plug DB- 9. Nhambwe yekukurukurirana yeRS-232 kazhinji iri mukati me15.24m.Kana tambo iri nani ikashandiswa, nhambwe yekutaurirana inogona kurebeswa.
