Mundane objects can have metadata embedded into them, or provide markers for augmented reality functionality, like tracking the object in 3D. How are the codes actually embedded?

Researchers have developed a way to include an unobtrusive edible tag embedded inside food—in their original experiments, cookies—that can be read without having to first destroy the food or impact ...

Researchers have developed a new method to embed information in a 3D printed object and retrieve it using a consumer document scanner.

You look below the model for the button “ Include ” to get your choice of embedding and the code snippet you copy/paste to your web site/blog (more instructions in link above).

QR codes are everywhere nowadays, but they don’t have to be. MIT scientists have developed an invisible tagging system called BrightMarker, which embeds fluorescent tags into objects that can be ...

Would you like a QR code embedded in that cookie? Researchers from Osaka University develop 'interiqr', a novel three-dimensional (3D) printing method of embedding edible QR codes--a type of ...

[Christopher Helmke] is doing fantastic work in DIY systems for handling small hardware like fasteners, and that includes robotic placement of hardware into 3D prints. Usually this means dropping nuts ...
