LinkSquare is a scanning device – a spectrometer – that compares reflected light spectrum from a pill to a reference scan recorded in a database.
Stratio has received some funding from the National Science Foundation and says it plans to start selling later this year for $199, initially through a crowdfunding campaign that is expected to start in June. The company also hopes to offer software developers tools to create their own applications for it.
To scale up, the company will build a database of medications.
From the comments to this MIT Review article, it seems this is not the only device of this kind.
