That article might be outdated. Even though using a card with a chip is even now becoming outdated technology, I put my card in the device as the cashier is beginning to scan the items. The device tells me when to remove the card , it would take a concerted effort on my part to make a mistake. By the time the cashier has finished scanning the items , the financial transaction is already done. I only have to wait for the receipt to be printed. Cash transactions do not even begin until the entire order has been scanned. The till must then be opened and, if necessary, change given which often only occurs after the elder woman has searched through the multitude of coins in her change purse, after searching through her purse to find the change purse among the multitude of other items she has stored there, to find the correct coins. If I have a small order, I will go to the self checkout and avoid waiting for others to be serviced first. By using a credit card, I not only do not have to deal with loose change at all but I also get the 1 to 5 % kickback from the credit card company. A win/win situation for me.
