3D-printed with scannable barcodes that you can’t see

 

A team of scientists from MIT and Facebook has have developed an object tagging system that’s invisible to the naked eye.

They plan to present their model, called InfraredTags, at the 2022 ACM CHI Conference on Human Factors in Computing Systems in April.

InfraredTags uses infrared light-based barcodes and QR codes that are embedded permanently into the bodies of 3D printed objects. A corresponding phone attachment with infrared cameras can be used to detect the code.
