Apple interested in transmitting information invisible to the human eye through the iPhone

We've frequently seen patents registered by Apple that are quite interesting. One of them reveals the company's interest in future iPhone displays, where they intend to find a way to transfer valuable information to other devices in a way that is invisible to the human eye.

The entire concept is detailed in the patent published this week, which describes how the screen can transmit data as an image that only another machine can read. This could be applied to the use of barcodes, applying coupons in stores, and that's being very naive, as Apple could use it for something much more interesting.

The system appears to work with different types of screens assembled so that one of them serves for communication between devices and another would be the one we normally know and interact with.

Another application being discussed regarding this new patent is using it to illuminate users' faces and surroundings as a facial recognition system that wouldn't require much light and wouldn't need to increase the iPhone 's screen brightness . Essentially, they're referring to an invisible light system.

The documentation is very interesting; however, it doesn't guarantee that this technology will be implemented in a future iPhone model anytime soon . It could arrive within the next few years, or it might simply remain in the company's files.
