Many call centers in the United Kingdom "routinely" record calls with consumers' credit card information, according to data compiled by Veritape Ltd.

The U.K. provider of recording center surveyed 133 call center managers in September, and found that only 3% comply with rules that prohibit the storing of credit and debit card information once transactions are complete.

About 61% of respondents said they were unaware of the rules, while 18% said they were "aware but … couldn't comply for technical or budgetary reasons," Veritape said.

Eleven percent of respondents said they ignore the rules, and 6% said they were working toward compliance.
