Tokenization technology has been available to keep payment card and personal data safer for several years, but it’s never had the attention it’s getting now in the wake of high-profile breaches. Still, merchants especially smaller ones haven’t necessarily caught on to the hacking threat or how tools such as tokenization limit exposure. That gap in understanding places ISOs and agents in an important place in the security mix, it’s their job to get the word out to merchants about the need for tokenization. That can begin with explaining what it is.
The biggest challenge that ISOs will see and are seeing, is this lack of awareness of these threats that are impacting that business sector. Data breaches are happening at small businesses, and even if merchants get past the point of accepting that they are at risk, they have no clue what to do next. Tokenization converts payment card account numbers into unique identification symbols for storage or for transactions through payment mechanisms such as mobile wallets. It’s complex and not enough ISOs understand it, even though it represents a potential revenue-producer and the industry as a whole is confused over tokenization standards and how to deploy and govern them.
ISOs presenting tokenization to merchants should echo what security experts and the Payment Card Industry Security Council often say about the technology. It’s a needed layer of security to complement EMV cards. EMV takes care of the card-present counterfeit fraud problem, while tokenization deters hackers from pilfering data from a payment network database. The Target data breach during the 2013 holiday shopping season haunts the payments industry. If Target’s card data had been tokenized, it would have been worthless to the criminals who stole it. It wouldn’t have stopped malware access to the database, but it would been as though criminals breaking into a bank vault found, instead of piles of cash, poker chips that only an authorized user could cash at a specific bank.
A database full of tokens has no value to criminals on the black market, which reduces risk for merchants. Unfortunately, the small merchants have not accepted the idea or the reality and fact, that there is malware attacking their point of sale and they are being exposed. That’s why ISOs should determine the level of need for tokenization in their markets. It is always the responsibility of those who are interacting with the merchant to have the knowledge for the market segment they are in. If you are selling to dry cleaners, you probably don’t need to know much about tokenization, but if you are selling to recurring billing or e-commerce merchants, you probably need a lot more knowledge about it.
Tokenization is critical for some applications in payments. Any sort of recurring billing that stores card information should be leveraging some form of tokenization. Whether the revenue stream comes directly from tokenization services or it is bundled into the overall payment acceptance product is not the most important factor. The point is that it’s an important value to the merchant to be able to tokenize the card number in recurring billing, but ISOs sell tokenization products against a confusing backdrop of standards developed for different forms of tokenization. EMVCo, which the card brands own, establishes guidelines for EMV chip-based smart card use. It’s working on standards for “payment” tokenization with the Clearing House, which establishes payment systems for financial institutions. Both entities were working on separate standards until The Clearing House joined EMVCo’s tokenization working group to determine similarities and determine whether one standard could cover the needs of banks and merchants.

Payment Tokenization Standards
Tokenization is the process of replacing a traditional card account number with a unique payment token that is restricted in how it can be used with a specific device, merchant, transaction type or channel. When using tokenization, merchants and digital wallet operators do not need to store card account numbers; instead they are able to store payment tokens that can only be used for their designated purpose. The tokenization process happens in the background in a manner that is expected to be invisible to the consumer.
EMVCo – which is collectively owned by American Express, Discover, JCB, MasterCard, UnionPay and Visa – has announced that it is expanding its scope to lead the payments industry’s work to standardize payment tokenization. EMVCo says that the new specification will help provide the payments community with a consistent, secure and interoperable environment to make digital payments when using a mobile handset, tablet, personal computer or other smart device.
Key elements of EMVCo’s work include adding new data fields to provide richer industry information about the transaction, which will improve transaction efficiency and enhance the consumer and merchant payment experience by helping to prevent fraudulent card account use. EMVCo will also create a consistent approach to identify and verify the valid use of a token during payment processing including authorization, capture, clearing and settlement.
EMVCo’s announcement follows an earlier joint announcement from MasterCard, Visa and American Express that proposed an initial framework for industry collaboration to standardize payment tokenization. EMVCo says it will now build on this framework with collective input from all of its members and the industry as a whole.
