MEMPHIS, Tenn. — Inside Roy Good Hardware on Lamar Avenue, owner Charles Nabors is used to making changes.

The business has been in his family since 1927, and a lot has changed since then.

“I’ve been getting calls and emails probably since about March — February or March,” Nabors said. “The first part of the year.”

Credit companies were calling to let the store owner know he would have to switch out his credit card machine for one that reads new chip technology.

Businesses that don’t make the switch by October could be liable for fraudulent purchases.

“It’s rather expensive,” Nabors said. “It’s not very cheap. We only have to use one credit card machine. So I would assume there are people who have to use several machines, and that can get very expensive.”

Nabors spent around $700 on his new machine that he purchased after his last one broke.

The price tag may be hard on some mom-and-pop shops in the Mid-South.

However, the store owner told WREG he wants the safest option for his customers no matter the cost.

“There’s no doubt about it,” Nabors said. “It’s much easier, the transactions are quicker, the customers seem to like it better.”
