RBS WorldPay said Wednesday it is back on Visa Inc.'s list of service providers that are validated as compliant with the PCI Data Security Standard.
Visa removed the Atlanta-based payment processor and Heartland Payment Systems Inc. from its list of PCI compliant service providers in March after data breaches at both companies were revealed. Heartland announced early this month that it was placed back on Visa's PCI compliance list.
RBS WorldPay, the U.S.-based payment processing division of the Royal Bank of Scotland Group plc, said it returned to both Visa's and MasterCard's lists of validated service providers following a successful completion of its PCI DSS assessment. The company said it's now certified on PCI DSS version 1.2.
In late December, RBS WorldPay disclosed that personal information of about 1.5 million pre-paid cardholders and other individuals was compromised when its computer system was hacked. The Social Security numbers of 1.1 million of those cardholders may also have been compromised, the company said.
The stolen data was used in a highly-coordinated ATM scam involving cloned payroll debit cards and reloadable gift cards.
The breach at RBS WorldPay was followed by Heartland's Jan. 20 announcement that intruders installed malware to pilfer data crossing the company's network.
