FRUIT THEMED Apple has applied for a patent on a digital handshake involving invisible ink.
The technology will involve using the integrated cameras on two devices to pair them together for a range of functions. This includes normal things like sharing files but also the ability to log on to one device using another or share information in a game, for example.
Patently Apple said, "Apple's invention is about systems, methods and computer-readable media for establishing a communications path between two devices using a digital handshake."
The image mentions 'next generation' cameras so it's possible that this technology will only work with future devices like the Iphone 5. Meanwhile rivals such as Google are using near field communications (NFC) for this type of feature.
Shiny fruit themed gadgets will be able to link with each other using invisible codes placed, possibly in various positions, around the device. And the system doesn't appear to be limited to only Apple products.
Using this combination of cameras and codes, a pair of products will be able to recognise each other from almost any angle including back to back, face to face and back to face.
Moving beyond just pairing two devices, the system could be used for things like retail situations. For example, the digital handshake could be used to get prescription medicine or authorise funds. µ
