On July 31, 2014, the US Patent & Trademark Office published a patent application from Apple that reveals new security control features for their future iWallet application. The new security system will work with an iPhone and Apple's iTunes Store on a Mac. The controls will allow parents to set boundaries for spending and track all purchases. Apple's patent also introduces us to the digital wallet processing engine. Last week a new rumor surfaced that discussed Apple's iWallet working with Visa's Digital Solutions sometime in the next year. Whether Apple's iWallet will make it to the iPhone 6 is unknown at this time.
