Braille Soda Cans, Regular Cans, and Jars

Blind people. Soda cans. Any other food cans. They don't mix.

Most food can be felt to determine what it is, but not cans. Many blind people have to get help to get the right type of canned food, and when they get home, they make up a little Braille card-label and stick it on the can.

This is highly irritating to the blind, trying to determine the contents of a can. Would it not be very simple to add little Braille dots onto the tops and lids of jars, describing the contents? I imagine they would find it highly useful.

I checked, and all I could find on this problem were that some blind people make their own labels and stick them on after they buy the product (with someone else's help).

Not only would this be useful for blind people, but also useful when fishing around in the icechest, if you do it fast before your fingers numb.
