In theory, you do not but until Apple perfects the technology, we'll just have to wait. I won't debate the merits of Bitcoin as a currency replacement as it is not needed, traded nor quoted in the financial markets. And by financial markets, I'm referring to the little club that certain banks and hedge funds have going between themselves, not the service your buddy operates from his apartment.
