3Delta Systems, Inc. (3DSI), a leader in online credit card payment solutions and the makers of CardVault®, an innovative credit card data storage service that removes a merchant’s risk of keeping confidential customer payment information, said today that a surprising number of businesses have yet to provide strong safeguards for protecting credit card holders' sensitive data and risk exposing that information to hackers. Forrester Research, for example, reported in its State of PCI Compliance study last fall that more than 100 million personally identifiable customer records have been breached in the U.S. over the past two years and that most of these breaches occurred at companies with household names. Forrester asked 677 information technology security executives from the U.S. and Europe about their data retention practices and found that 81% store credit card numbers, 73% retain card expiration dates and 71% keep verification codes on file.
