The use of a tokenization solution does not eliminate a merchant’s need to validate compliance with the Payment Card Industry Data Security Standard (PCI DSS), the industry group responsible for managing payment security guidelines said in a new document released Friday.

“The misconception is that I can buy one of these [tokenization solutions] and be PCI compliant,” Bob Russo, general manager of the PCI Security Standards Council, told SCMagazineUS.com. “That’s not the case.”

A mature and properly deployed tokenization solution can, however, simplify the requirements of PCI DSS by taking systems that no longer contain sensitive credit card numbers out of the scope of the standard, according to the 23-page supplement released by the PCI Council.

Meanwhile, Sue Zloth, product group manager at payment data security provider Merchant Link, a member of the PCI Council’s tokenization task force, told SCMagazineUS.com on Friday that she believes the document is a good first step, though it may lead to some confusion and deter adoption.

Zloth took issue with a section that discusses the need to evaluate whether a token itself could be used – in lieu of cardholder data – to perform a transaction.

The document states that so-called “high-value tokens,” which can be used as a form of payment, could be monetized by an attacker or used to generate fraudulent transactions.

The council introduced a valid concern –  that certain tokens could be valuable to attackers — but “fell down” by failing to describe how a tokenization system could adequately protect tokens from being fraudulently used, Zloth said.

“A properly implemented system will know who is sending transactions and will not allow anyone to send transactions with a token,” she added.
