Amongst some of yesterday's seemingly minor Apple granted patents was one that I almost overlooked. It seemed like a patent describing Apple's SIM card slot assembly and no more. Yet under closer investigation, it became clear that Apple has their eye on expanding the use of their ejectable component assembly. The patent points to other future applications such as memory cards or perhaps a tiny SD card. But the real eye opener here is that Apple is considering integrating things like microprocessor or integrated circuit cards. That translates into how the iWallet component will come to be in the iPhone, iPod touch, iPad and other future miniature devices. You'll simply pop your mini-credit card chip into one of these protected ejectable assemblies just like you do today with a SIM card.
