Michaels has discovered that PIN pad machines were tampered with at 90 of its stores nationwide, including the store in Lynnwood. The company says customer credit and debit card information may have been compromised.

Michaels was contacted by banking and police officials after fraudulent debit card transactions were reported. They checked the PIN pads at all of their 964 stores and found that 90 of them had been tampered with.

“Consumers who have purchased items from a Michaels store with a debit or credit card are encouraged to monitor their statements, report any suspicious account activity, and change any PIN numbers and other account security settings,” the company said in a statement.

The company has started replacing PIN pads in all US stores and expects the replacement to be completed within about two weeks. Until then, customers can have their credit and signature debit transactions processed on the store’s register.

The stores in Everett, Marysville, Kirkland and Tukwila are also affected.
