Nakup z magnetnim zapisom z MC obročno shemo na Verifone Vx520 POS terminalu

ŠEME, MATEJ (author), Šajn, Luka (mentor)

Idejo diplomske naloge sem dobil v službi na podjetju Printec S.I. d. o. o. Tam sem imel tudi obvezno prakso v tretjem letniku. Ker so me kasneje zaposlili, saj so potrebovali dodatno pomoč pri POS plačilnih terminalih za produkcijo v letu 2019, sem se za nakup z MC obročno shemo odločil zato, ker je bila naloga bolj obsežna. Najprej sem moral spoznati strukturo ter arhitekturo obstoječe POS aplikacije, ki so jo izdelali v Printec Romuniji, nato razumeti vse zahteve MC za obročno shemo ter pravilno obnašanje terminala. Sledila sta programiranje oz. izdelava funkcionalnosti. Po združitvi izvorne kode je bilo potrebno obsežno testiranje, da nikakršna sprememba ni vplivala na že obstoječe delujoče funkcionalnosti. Ko je bilo vse pravilno implementirano, je sledilo ponovno testiranje zaposlenih na Bankartu, da so preverili pravilnost delovanja. Potek vsakega koraka je podrobneje zapisan v diplomskem delu, ki se najprej začne z razumevanjem arhitekture POS aplikacije ter njenega delovanja. Nato sledi implementacija plačila z MasterCard obročno shemo, če je na voljo.

Abstract

I got the idea for the thesis at work in the company Printec S.I. d.o.o. I also had mandatory practice in the 3rd, the final year. Later they employed me because they needed extra help with POS terminals which should be ready for the production in 2019. Since this task was more extensive, I decided I will take it for my thesis. Firstly, I had to learn and understand how existing application works since the framework was done in Printec Romania. Then, I had to read and understand all the MasterCard requirements for installments and how should POS terminal behave during the transaction. After that, it was a programming described functionality. When the code was done, it was merged into the existing solution and thoroughly tested and fixed where needed since the added feature must not break something which has already worked. Later, it was tested again by Bankart, i.e. ATM and Card processing Center in Slovenia. How each step was done, it is explained in detail later in the thesis, firstly, with an explanation of the framework used for programming and after that with implementation for MasterCard installments payment option, if there is such an option.
