On July 12, 2012, the US Patent & Trademark Office published a patent application from Apple that reveals their intent to build an ejectable tray into future iDevices, including the iPod touch, which will accommodate specialty modules such as a smart card. Apple has updated this patent which was actually granted to them in March of this year. The activity involving this patent is a great sign that Apple may be putting the final touches on this feature before bringing it to market. The European Telecommunications Standards Institute (ETSI) recently approved Apple's Nano SIM which opens the door for Apple's future iWallet application to come to market. Apple's current patent goes beyond just smart cards and will allow future iDevices to store data on flash cards and beyond.
