Visa warns software may store customer data Tech News on ZDNet

A popular software that retailers use to control debit-card transactions may inadvertently store sensitive customer information, including PIN codes, says Visa.

Two versions of cash-register software made by Fujitsu Transaction Solutions are under scrutiny, according to a warning Visa issued to the companies that process card transactions for some of the nation's largest retailers. A Visa representative confirmed that the warning was sent.

Some of Fujitsu's retail customers include Best Buy, Staples and OfficeMax, but it is not known which companies use the software Visa claims is flawed.

Visa's warning, which was first reported by The Wall Street Journal on Friday, has raised eyebrows in the financial and retail sectors. The software was flagged at a time when thousands of debit-card holders across the country have reported unauthorized withdrawals from their accounts.

Thanks to Slasdot for the pointer.
