Statistics show that younger people buy more than middle-aged people. They also show that younger people use the newest technology and that means smart phones, i-pads, credit/debit cards and shopping on the internet. Your company simply has to use credit card processing in order to get a share of the younger market.
Polls taken show that younger drivers in their twenties preferred paying a few extra cents per gallon at a gas station that would take their debit card, to saving a little money if they brought in cash. They analyzed the effort that it would require to go to the bank and get the cash, not spend it on other items, and bring it to the other station, and stuck with their debit card habit.
