Ngokuthuthuka kwezinga lokuphila kwabantu, abantu banaka kakhulu ikhwalithi yensizakalo ngakho-ke le mishini yokuzi-oda ifika emehlweni abantu kulo mongo. Ngokuthuthukiswa kwesayensi nobuchwepheshe ngokuqhubekayo kunciphisa izindleko zehadiwe, ukuqaliswa kwalezi zinhlelo kuyenzeka. Kulezi zinsuku, izixazululo zemishini yoku-oda esetshenziswayo, njengama-PDA's aphathwa ngesandla, ziya ngokuya zingena emabhizinisini ajwayelekile okuphekela.
Umshini we-Self-service oda kaLILLIPUT usebenzisa isisombululo se-PDA esiphathwa ngesandla, lokhu kungagcwalisa i-oda lemenyu lokuziphilisa eliphelele ngaphandle kokubandakanyeka kuweta / uweta. I-oda lidluliselwa ngenethiwekhi kuseva emaphakathi ngesikhathi sangempela. Lokhu kusiza ngezikhathi zokudlela ezimatasa, konga ukwakhiwa kwemenyu nezindleko zokuphrinta, ngenkathi kuvumela ukuvuselelwa kwemenyu okusheshayo futhi kuncoma / izitsha ezikhethekile. Uhlelo lungafakwa etafuleni lokudlela noma eduze futhi luxhunywe kwi-POS yangaphambili yendawo yokudlela. Indawo yokudlela inga-oda futhi ikhokhe umthethosivivinywa futhi ibheke nesimo sokulungiswa kwe-oda, idlale imidlalo noma okunye ukuzijabulisa, ibuye ibuke nezikhangiso ngenkathi ilinde uku-oda kwayo.
