A former Home Depot Inc. employee in Texas must serve 18 months in federal prison for stealing credit card numbers from nearly 37,000 customers.
Daniel Marquadt of Round Rock was sentenced Friday in Austin.
Marquadt, who did information technology work for Home Depot in Austin, pleaded guilty in November to trafficking in stolen devices.
Investigators say Marquadt wrote a computer program to help Home Depot with its tool rental system, then realized he had access to personal data of customers.
An online security firm noticed an offering to sell credit card numbers. An undercover investigation involving agents from Atlanta, where Home Depot is based, led to Marquadt.
Marquadt told the Austin American-Statesman that he sold about 100 credit card numbers but never collected any money.
Home Depot didn't immediately comment.
