Where are the microchips embedded?

It’s called “ubiquitous computing,” literally computers everywhere. And in Japan it’s being tested to track food safety, from sushi to cabbages. These vegetables have microchips embedded in the packaging. So customers can access endless amounts of information about the products they buy, from pesticides to recipes. It starts here. Farmers input data as they tend their crop. Harvest dates, fertilizers, even genetic modifications, anything the customer may want to know. Then it goes for packaging. Every item gets a microchip, a tiny computer that wirelessly projects a unique ID code.
