FORTUNE — “Mobile payments remains a future opportunity,” wrote Morgan Stanley’s Katy Huberty in her note to clients about Monday’s WWDC keynote.
And sure enough, on Tuesday morning the U.S. Patent Office granted Apple (AAPL) 37 patents that included, as Patently Apple reports, an “E-Wallet” patent for parental controls and a “simplified wireless data transfer” patent that would allow an iPhone to make mobile payments without relying on NFC (near field communication) technologies.
Of course, just because Apple patents a technology doesn’t mean it will develop it. But at this point the company has amassed quite an arsenal of patents covering mobile payments. Patently Apple has collected them in its Archives.
