TechCrunch is reporting on Apple’s testing of wireless payment systems today. If you’re unaware of what NFC (near field communication) is, it’s pretty cool — it allows for credit/debit transactions to happen wirelessly using short range transmission. They’re using prototype iPhones to do the tests, which, if they go will, could signal the technology as a feature in the iPhone 5. The tech could also be used to wirelessly transfer photos and video from your iPhone to your MacBook almost instantaneously, or to give people coupons based on being at a certain location at a certain time. Hopefully we’ll be seeing this tech become prevalent soon.
