Edible QR codes are already a reality. And you have many interesting applications. Without using paper or labels!
Researchers at Osaka University have created a new technology called interiorwhich allows you to print a QR code within the foods, without the need for a label. A edible qr code for the first connected foods.
This QR code could be very useful to show the expiration date of the food, the ingredients, the batch number, or if it contains any allergens.
From a marketing point of view, it can be used to display advertising messages, logos, prizes, game downloads, etc. authentic connected foods.
The most interesting of all is that interior does not alter the flavor or the external appearance of the food, since the QR code is created with the product’s own ingredients. You can see it in the opening video of the news.
Edible QR Codes
In fact, the technology used by these researchers from the osaka university, it is quite simple. What they have done is use a 3D food printer to print QR code cookies that you want to use. Then an additional layer of dough has been added to the cookie, and it has been baked.
On the outside, the cookie is identical to the rest, but if we put it in front of a window or a light bulb, it becomes transparent, and allows us to see the QR code. All that remains is to focus it with the mobile camera, to read the QR code that contains the information.
As we can see, the system is simple, although it has some obvious limitations. In order to use the food you must use ingredients that can be printed with a food printer. Basically pasta, flour dough, etc.
In addition, this food must be semitransparent to light, to let him see edible qr code inside.
It’s an interesting idea that can have both practical and marketing utility for very specific foods.
Interiorthe edible QR codes, allow you to insert QR codes inside food, such as cookies, legs, cakes, and many others. are the new connected foods. Will we see them soon in supermarkets?
