I have seen the future of food transparency, and it is optical. Also, it fits in your smartphone.
Imagine a scanner the size of a grain of rice, built into your phone. You go to the grocery store and point it at something you want to buy. If it’s an apple, the scanner will tell you what variety it is, how much vitamin C it has and how long it has been in cold storage. If it’s a fish, you’ll learn whether it’s really orange roughy or just tilapia being passed off as something more expensive. If it’s a muffin, the device will tell you whether there’s gluten in it.
Will you offer us a hand? Every gift, regardless of size, fuels our future.

Thank you.
Although you won’t be able to do it tomorrow, this isn’t some kind of distant Jetsonian vision of the future. I’ve held the rice-size scanner in my hand; it was built for only a few dollars. I’ve seen bigger, more robust versions of the scanner do the things that your smartphone will be able to do, probably during the administration of the president we’re deciding on right now.
