About 2.6 million credit and debit cards used at Michaels arts and crafts stores, including the location in Lawrence, were breached during a hacking incident last year, the company announced this week.
Michaels Stores Inc. said the breach represented about 7 percent of sales at its locations from mid-2013 to early 2014, and a "limited" number of customers have reported that their cards had been used fraudulently.
In Lawrence, the incident affected customers who made purchases with a credit or debit card at the Michaels store at 3106 Iowa St. between May 8 and July 29. However, it is unknown exactly how many cards were impacted at the Lawrence outlet.
"Michaels cannot identify individual affected customers based on the payment card data the company has available," said company spokeswoman Kim Paone. "If customers believe their card was affected or they see unusual activity on their payment card statements, they should immediately contact their bank or card issuer."
While the company said credit and debit card numbers and expiration dates were compromised in the incident, it has found no evidence that customer names, addresses or PINS were obtained by hackers.
