RFID seems pretty interesting. I saw some report on CNET (can't find it now) recently where a Korean company had developed RFID paper. That opens up things like anti-counterfeit measures for tickets to sporting/entertainment events, ensuring memos on corporate/goverment letterhead is genuine, etc. Also, many casinos are starting to use RFID's in chips to prevent cheating and fake chips, and also to have real-time info on wins/losses at the tables.
It's a pervasive enough technology that you could find some application in an area that interests you - which always makes writing papers easier.
Good luck! Don't be in too much a rush to join the real world. There's less co-eds out here in IT (or maybe you're one youself. In that case - welcome!).
