Though companies like Visa and Device Fidelity have already come up with a way to make NFC payments via microSD card, the SD Association (the standardization body for SD cards) has introduced a spec that opens up that ability to others. It essentially adds the single wire protocol (SWP) as a Secure Element to enable NFC authorizations like mobile payments and identity verification. Now that any of its members can implement the standard to their microSD cards, perhaps some day we can truly replace our wallets with our phones. We've included the press release and a short video demo after the break if you feel like understanding the tech a little better.
