BARCODE READER OF THE PRODUCTS WITH THE SMARTPHONE

V diplomskem delu smo predstavili aplikacijo za pametne mobilne telefone, grajeno za operacijski sistem Android. V današnjem času je veliko trgovcev, ki svoje artikle ponujajo po različnih cenah. Za lažji pregled njihovih cen smo izdelali aplikacijo »Kupuj pametneje«. Aplikacija »Kupuj pametneje« omogoča branje črtnih kod preko kamere in posredovanje informacij o cenah artiklov pri različnih trgovskih verigah. Aplikacija se povezuje z bazo MySQL, kjer so hranjeni podatki o cenah. Grajena je s pomočjo razvojnega okolja Eclips. Za posredovanje podatkov iz baze smo uporabili strežniški skriptni jezik PHP. Ker aplikacija deluje na osnovi bralnika črtnih kod, bomo v uvodnih poglavjih predstavili vrste črtnih kod, njihov namen in uporabo. V drugem delu diplomske naloge bomo obravnavali operacijski sistem Android in predstavili implementacijo aplikacije.In our thesis we will present an application for smart mobile phones, programmed for Android operating system. Nowadays there are a lot of merchants that offer their products at different prices. To obtain an easier review of their prices, we have created an application called "Buy smarter". Application "Buy smarter" allows you to read bar codes through the camera and supplies you with the information about prices of various products in different store chains. The application connects to a MySQL database where the price information is stored. It is programmed using the development environment Eclipse. For transferring data from the database we used a PHP scripting language server. Since the application is based on bar code readers, we will introduce the types of bar codes, their purposes and uses in the introductory chapter. In the second part of the thesis we discuss the Android operating system and present the implementation of the application
