How to improve local food

Make local supermarket and grocery stores sales data available online so that local food managers can access them for a fee. By studying the data on grocery sales from all supermarkets and stores in the area food managers will get a pretty good idea of people's preferences. For example, if your local food deli or restaurant sells pasta you can find out from sales data which types of spaghetti sauce people in your area buy the most. First make sure that you offer them in the menu and then work on improving their taste.

baskets with scanners

a way to save time is to put scanners on supermarket baskets to show customers the total cost of all items in it. this way customers would know if they are about to overspend and when ready they just pay at the cashier or swipe their credit card on the side of the scanner for faster payment.

award points directly into the credit card

the problem with retailers' cards is that each retailer awards its own card and people end up carrying too many of them. since every retailer accepts credit cards, credit card companies should allow for an additional magnetic bar or chip to be added at the back of the credit card that will store any and all retailer's points (gas station, supermarket, groceries, malls, airlines etc). swipe the card once so that the scanner reads the balance and gives the discount, swipe it once again to make payment.
