Saving time at the grocery store

I hate waiting in line at the grocery store. It’s really frustrating to wait in line for such a long time when it should be a smooth process. Right now, what we do is, we get a shopping cart as soon as we enter into a grocery store. We do our groceries. And then we have to stand in a long line to pay for the items that we bought. Unless you are lucky enough, you might have to wait somewhere between 10-15 minutes to pay off. It takes such a long time because the lady at the counter is swiping each and every time that we bought through the scanner. That process can be reengineered. We could have an installed scanner with the shopping cart. And as we take each item and put it into the cart, we swipe it through the scanner installed at the shopping cart. And then as we reach the counter, the lady at the counter only have to take the payment, saving her the time to swipe each and every item that we bought. Thus, it will save lots of time, money and effort, both for the buyers as well as for the sellers.
