Braille Seal / Braille Seal

Eating expired food will cause cancer, for the blind, they cannot see the shelf life on the packaging, it is difficult to determine whether the food is expired, eating expired food aby mistake will affect health. We designed a braille seal to solve this problem, by asking the salesman, the blind can know the shelf life of the food, press the Braille stamp button and input the date by voice, at the end of the seal will generate a solid rubber material Braille date, and then seal it on the food packaging to help the blind to identify the shelf life.
