Sažetak

Tehnologija beskontaknog čitača danas je u širokoj primjeni. Primarno zbog zahtjevanog i brzog razvoja postoji mnoštvo industrijskih standarda za ostavrijavnje komunikacije izneđu čitača i poslužitelja. Mnoštvo standarda uzrokuje može se pretvoriti u značajan problem ako nabavka istoga čitača postane problematična odnosno čitač postane nedostupan ili se više ne proizvodi. Predlažemo novo rješenje uvodeći mikrokontroler pri čemu je omogućena ozrada vlastitog sklopovskog sučelja i protokola komunikacije. Navedeno rješenje omogućava izradu nedostupnog čitala prema njegovim specifi kacijama kao i razvoj novog lako nadogradivog rješenja.

Abstract

Radio frequency identification solutions are widely used today to enable user identification. Due to rapid development, a large variety of standards is deployed by manufacturer to enable reader communication with computer system. Th ese diff erences can become a problem if the reader becomes deprecated or unavailable. A new solution is proposed to introduce microcontroller which enables custom interface and protocol development. Th is solution enabled emulation of unavailable readers and development a new line of constantly available and adaptable reader solution.

Patrik Ervells latest collection is ironically titled “Software”ADIDAS ORIGINALS TUBULAR SHADOW. In the notes from the presentation, Ervell says he was interested in developing tension between nostalgia and sci-fi,NIKE ZOOM WINFLO 3 and even included 90s cyberpunk amongst his influences. Ervell developed this point of view by creating an imaginary software company called Idegen software systems. He then re-appropriated the company’AIR JORDAN XXXI MENs logo in several of the collection’s garments. Elsewhere,MBT TARIKI MEN mohair coats with oversized lapels made an appearance alongside mock neck tees,NIKE AIR JORDAN RETRO 5 police-inspired ribbed sweaters,MBT FORA GTX WOMEN flight bombers, and polyurethane leather coats. The setting was also suitably dystopian, and the resulting ambiance was something akin to if the creators of Deutschland 83 and Hackers met up and decided to create a collection… We mean that as a compliment.Yesterday afternoon,JORDAN CP3 IX MEN artist JR spent the day working on his latest collaborative piece with Daniel Arsham in Greenpoint,NIKE AIR MAX 90 Brooklyn,MBT KIMONDO GTX MEN NYC. Connecting the lines between art, architecture, dance and theater, Daniel Arsham has been known to subvert existing architectural structures in unconventional,NIKE CLASSIC CORTEZ NYLON playful ways; confusing and confounding the expectations of space and form.
