Barnes & Noble detected credit card tampering in its Robinson Township store, according to a company news release.
The national book retailer found evidence of tampering with devices used to process debit and credit card transactions at 63 of its stores across the country, including its location in the Settlers Ridge shopping complex.
The tampering was an effort to steal credit and debit card information from customers.
As a result of the tampering, Barnes & Noble discontinued use of more than 700 PIN pads in its stores. Fewer than 1 percent of the store's PIN pads were compromised.
From the company:
"Barnes & Noble is continuing to assist federal law enforcement authorities in this matter. In addition, the company is working with banks, payment card brands and issuers to identify accounts that may have been compromised, so banks and issuers can employ enhanced fraud security measures on potentially impacted accounts."
The Barnes & Noble company database is secure and tampering did not involve Nook devices or Nook mobile apps, according to the company statement.
Online purchases were not impacted. Federal law enforcement is investigating.
