An Invisible QR Code System May be Used to Track Objects in the Near Future

3D-printed items can soon be tracked thanks to a system of invisible QR codes created by researchers at the Massachusetts Institute of Technology (MIT). 

With its practical uses, this technology may be used for everything from creating virtual reality video games to identifying objects in the event of theft.

An invisible QR code system may be used to track objects

Under the name BrightMarker, this invention is actually a brand-new, invisible marking technique that uses fluorescent filaments that are simple to find in 3D-printed things.

It is now undergoing testing in the lab. 

The answer takes the form of fluorescent tags that are incorporated into actual items and are intended to detect and monitor their motions.

As a result, these "tags" are incorporated into the object from the very beginning of its creation and cannot be added to already existing objects. 

An infrared camera captures the entire procedure. 

Actually, the researchers have created two hardware configurations that can identify these BrightMarkers: one for virtual and augmented reality headsets and the other for smartphones.

Thanks to this special invisible coding, recovering stolen things may be identified—possibly the most apparent use. 

For example, BrightMarkers are less costly and use less energy than Apple's AirTags tracking devices. 

They may also be applied to products as a distinct digital signature to confirm their provenance and subsequently update recycling data.
