A new survey shows that data security is a significant issue for community banks.
The survey was conducted by America's Community Bankers, a national trade group; in analyzing results, a group official cited TJX Cos. of Framingham, which operates retail chains such as T.J. Maxx and Marshalls.
Last month, TJX disclosed that a hacker had broken into its computer system, potentially exposing millions of customer credit card and debit card numbers.
According to the bank group's survey of its members, 70 percent said their bank had to reissue credit or debit cards three times or more in the past 24 months.
"These survey results, released with the backdrop of the recent TJX data breach, underscore the need for immediate attention from Visa and MasterCard and congressional action," Michael T. Crowley Jr., chairman of the group's debit-card fraud committee, said in a statement.
