20.500.12556/RUL-30858 Brezkontaktni sistem plačevanja z mobilnimi NFC napravami Contactless payment system with mobile NFC devices Mobilne storitve predstavljajo enega od načinov zamenjave klasične plačilne kartice s pametnim telefonom in tehnologijo NFC (Near Field Communication). Pojavljajo se različne ideje kako izvesti gotovinske transakcije med dvema NFC napravama, brez vsakokratne povezave z zalednim sistemom, v katerem ima uporabnik svoj bančni račun. Cilj magistrskega dela je bil razviti sistem za demonstracijo in izvedbo brezkontaktnega plačevanja, ki temelji na uporabi elektronske gotovine. Njegova izvedba je razdeljena na strežniški del, ki predstavlja bančni sistem in uporabniški del, ki omogoča izmenjavo gotovine v nepovezanem načinu. Anonimno plačilo poteka med dvema mobilnima napravama Android s pomočjo komunikacije P2P (Peer-to-Peer) v tehnologiji NFC. Zasnovani in implementirani so postopki, ki omogočajo dvig in polog elektronske gotovine med mobilno aplikacijo in bančnim sistemom. Zagon aplikacije je omogočen z vpisom poznane kode in preverjanjem kartice NFC, varnost podatkov na napravi pa je zagotovljena s šifriranjem. Za detekcijo dvojne porabe je izveden postopek, ki omogoča beleženje podatkov o položeni elektronski gotovini. Mobile services represent one of the possibilities for replacing traditional payment cards with smartphones and NFC (Near Field Communication) technology. There are different ideas how to implement cash transactions between two NFC devices without respective connection with system of a user’s bank. The aim of the master’s thesis was to develop a system for demonstration and realization of contactless payment, based on electronic cash. The implementation of a system containing the server part which represents banking system, and the user application that enables the exchange of the electronic cash in offline mode. Anonymous payment is performed between two Android mobile devices via P2P (Peer-to-Peer) communication in NFC technology. The procedures for withdrawing and depositing of the electronic cash between the mobile application and the banking system are designed and implemented. It is possible to launch the application by entering the user’s PIN code and checking of the NFC card. Data security on a mobile device in ensured with the encryption. The procedure that enables the recording of a data about the deposited electronic cash is carried out and tested with the history data to detect double spending. brezkontaktno plačevanje elektronska gotovina NFC P2P pametne mobilne naprave contactless payment electronic cash NFC P2P smartphones true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2015-07-06 13:30:06 2015-07-06 13:30:07 2022-08-01 11:17:57 0000-00-00 00:00:00 2015 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 14091 Jagodnik_Tadej_-_Brezkontaktni_sistem_placevanja_z_mobilnimi_NFC_napravami.pdf Jagodnik_Tadej_-_Brezkontaktni_sistem_placevanja_z_mobilnimi_NFC_napravami.pdf 1 2BFD0B07988BC8A0264E8ECAD4F7E4C0 2ae552c68cd306ab32c490e2cb98ffb94c3d77fb2c5ee3068c75662063616d29 549fef41-a1ad-11eb-a523-00155dcfd717 20.500.12556/rul/d87cb2de-c965-4aa9-a0fc-ee0d376bb19a https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=30867 Fakulteta za računalništvo in informatiko 0 0 0
