Safeguard Your Food / Safeguard Your Food

Safeguard Your Food

Have you ever bought expired or nearly expired food?Although we usually notice the valid date of food before purchase,sometimes we still forget to do it.We start to think and find the solution to this problem,so we designed a new bar code system. When you pay for expired food,the cash register will show you "Unable to buy",so we can avoid buying expired food. We put the valid date on the bar code so that the product's content and valid date will be shown on the screen when customers pay.When scanning the bar code,the product information will appear. It will be unable to be bought when the product is expired.
