How To Implement A Credit Card Tokenization Service

What is Credit Card Tokenization?

Now that you know about the basics and benefits that come with credit card tokenization, you may begin to wonder how you can implement a tokenization system of your own. If youre worried that implementing credit card tokenization may be too complicated, you may be pleasantly surprised to discover that the reality is quite to the contrary.

The most straightforward way that retail businesses can start implementing their own tokenization system is by obtaining a near-field communication credit card reader. Pay apps that integrate with NFC card readers already include tokenization as a built-in component and dont require that merchants purchase any additional hardware aside from a new NFC reader.

Merchants can also begin their implementation process by connecting with their processor or gateway provider. These providers can often either put merchants in touch with their tokenization software partner or provide guidance themselves on the typical steps to take to implement credit card tokenization:;

  • The credit card tokenization implementation process is merchant-friendly and usually requires little to no new investments in hardware. To begin, discover any legacy data that resides on your network and convert that data to tokenized alphanumerics. This step isnt necessary for merchants who dont already store actual customer payment data after they complete their payment authorization.
  • Create A Wrapped Encryption Key For Dlp Tokenization

    If you intend to use DLP tokenization, you will be supplying your own data encryption key . In this step, you create adata encryption key and then wrap it in an additional layer of encryption called the key encryption key . Note that the KEK is fully managed by KMS and never leaves the service. Key wrapping is technically optional for testing DLP tokenization but should be a security requirement for production environments.

  • Create a KMS keyring. Note the keyring name and location .

  • Create a key for that ring. Note the key name.

  • Copy and open the local.envvars file to configure the token wrapping utility:

    cp examples/envvars examples/local.envvarsnano examples/local.envvars

    Populate the variables KMS_LOCATION, KMS_KEY_RING, and KMS_KEY_NAME with the values noted in the previous steps.

  • Generate the keys.

    There are many ways to generate random bytes. This command will use the Linux system’s random number generator to generate 16 hexadecimal bytes ; it creates two files: key_##B.txt and key_##B.wrapped.txt:

    LEN=32openssl rand $LEN | tee key_$B.txt | examples/wrapkey | tee key_$B.wrapped.txt
  • Preserve the wrapped and unwrapped keyfiles along with the KMS key details.

  • Grant permissions to the invoking service account:

  • Edit permissions of the Compute Engine default service account.It should look like this: 000000000000-compute@developer.gserviceaccount.com.
  • Grant the role DLP User.
  • What Is The Difference Between Credit Card Tokenization And Encryption

    When we talk about these credit cards and how these credit cards are stored, are two ways. Can you tell us more about this?

    You can either encrypt them into your system or tokenize the credit cards. When we are tokenizing the credit cards, you need to use a payment provider like Worldpay or there are a bunch of other payment providers out there like Authorize.Net.

    The tokenized credit cards are handled by the payment provider. However, if you are storing the credit cards in an encrypted fashion, solutions are out there. PCI compliant platforms like Volusion, BigCommerce, and Shopify actually handle this for you. Then it gets a little complicated because there are two types of recurring credit cards you can have.

    One, you can have a recurring product or reoccurring order. The challenge comes when a platform like Volusion really handles recurring orders, not products, and a solution like BigCommerce can handle recurring products and recurring orders.

    These platforms cover different scopes. Because if I am buying only one product on Tuesday the 19th, that charge is going to hit me every 30 days. If Im buying another product now on the 22nd, however, does the token or encrypted credit card merge those two products into one order? Do I treat it as separate products?

    Frequently Asked Questions About Payment Tokenization

    A tokenized transaction uses an alphanumeric token to substitute a cardholders primary account number during a transaction. A tokenized payment transaction doesnt transmit a primary account number and instead replaces sensitive cardholder information with a token.

    Tokenization is used for protecting cardholder information during the process of a payment transaction. Merchants use tokenization when they dont want to store sensitive cardholder information on their POS system.

    Credit card tokenization reduces PCI scope by removing sensitive cardholder data from a merchants environment. Tokenization makes it so merchants dont need to worry about storing sensitive information on their internal POS system and suffering data breaches.

    The benefits of tokenization for merchants include a reduced risk of data breaches, a smaller scope of PCI-DSS compliance to worry about, and multiple payment processing methods for customers who want to complete transactions both online and in-person.

    The main difference between tokenization and encryption is that credit card tokenization generates a token based on the primary account number of a cardholder, while encryption encodes sensitive cardholder data using a mathematical algorithm.

    Save The Credit Card Token To The Reservation

    Know Your Payments » Tokenization

    First, lookup the reservation ID in the Navigator of the relevant reservation.

    Open the Tokenizer and enter the credit card data .

    Enter the reservation ID .

    Figure: protel Cloud Center > PCI > Tokenize. Enter the credit card data + reservation ID

    The credit card token will then be saved in the Navigator afterwards. It can also be accessed in the “Credit Card Authorization” dialog box located in the “More…” dialog box.

    ;Please note

    Currently, credit card tokens can also be assigned to a profile, which, however, violates the latest PCI specifications.

    For this reason, tokens attached to a profile are deleted by the purge routine after every end of day process.

    We therefore strongly advise against storing tokens in the profile.

    Detailed description of the dialog box

    All fields with * are mandatory


    The credit card type will automatically appear once the credit card number has been successfully entered.


    The token is displayed here once the credit card information has been tokenized .

    Explanation: Rather than using real credit card numbers, protel solely uses tokenized numbers. The sensitive original data are stored on the external tokenization server where they are protected from unauthorized access.

    One Card Multiple Payments

    What is Credit Card Tokenization? | Helcim FYI

    Let’s start with an EMV tokenization definition.;

    EMV Tokenization is the process of digitizing a single physical payment card into several independent digital payment;means through tokens.

    And understand its flexibility.

    EMV Tokenization is extremely valuable in a context where we are using an ever-increasing number of wallets supporting multiple channels and payment use cases.

    The same credit card can have as many tokens as the end-user has enabled devices – such as smartphones and wearables, and wallets such as OEM-Pays.;

    Besides, as the EMV tokenization is omnichannel, it can be used for in-store, in-app, or online payments. It all depends on the individual usage scenario.

    There’s more.

    Tokens simplify life-cycle management because they can be suspended or deleted for a particular usage or device without impacting any other tokens in use they are entirely autonomous.

    Recurring Transaction Rate Comparison


    To put it bluntly, you are literally giving away money if you are failing to properly flag transactions as recurring. You need to make sure your website is coded correctly , and that your credit card processor is flagging the transactions properly so the reduced interchange rate is identified and passed back by Visa and MasterCard.

    Another important note to make sure you see the cost savings is to make sure that you are getting interchange plus pricing from your payment processor. If you are not on an interchange plus pricing model your payment processor almost certainly won’t pass on the savings. At Merchant-Accounts.ca we always recommend interchange plus pricing and will work with you to try to make sure your transactions qualify for the recurring billing interchange wherever possible.

    Additional Benefits Of Credit Card Tokenization

    Security and risk reduction are tokenization’s primary aim, but the compliance benefit of using tokenization to reduce controls and remove sensitive data from scope can be just as valuable. By replacing sensitive cardholder data with an irreversible token, tokenization effectively removes sensitive data from a cardholder data environment. Because tokens are considered nonsensitive data, they can be stored and used for internal business purposes without bringing the system that stores them into scope.

    In some instances, this level of scope reduction can be so great that an ecommerce web store, for example, can potentially use TokenEx’s Cloud Security Platform to reduce its compliance obligations to a SAQ-A. The SAQ-A is a self-assessment covering only requirements 9 and 12 of the PCI DSS, which entail restricting physical cardholder access to sensitive data and maintaining an information security policy, respectively. This means an organization would outsource all of its other PCI DSS requirements and be responsible solely for requirements 9 and 12, resulting in significant savings in terms of overhead and operations.

    Is This The Same As Emv Technology

    The EMV chips embedded in modern credit cards operate on the same general principle. The chips generate a unique, one-time-use code for each purchase. But EMV chips work only with in-person transactions. When you give your number to an online merchant, the chip doesn’t do anything. When an online merchant is using tokenization, though, your card data has protection similar to that offered by an EMV chip.

    For an example of a system that uses tokenization, look at your phone. Apple Pay, Google Pay and other digital wallets operate on a tokenization system. Your credit cards aren’t really “stored” in the digital wallet. What are? Tokens that link to your card information. These tokens don’t work exactly like merchant tokenization, but the concept is the same.

    What is Tokenization and How Does It Work

    Tokens ensure a seamless, secure digital transaction process. Credit card tokenization makes it easy for merchants to protect customer accounts from fraud. It creates a frictionless, card-free experience that makes eCommerce purchases easier and more commonplace and allows for secure, in-app mobile transactions so people can purchase what they need, when they need it, on the go.

  • Step one: Credit card tokenization transactions begin with the cardholder. The cardholder initiates the transaction either online, in-store, or in-app by providing their credit card information.
  • Step two: The merchant passes a token on to the receiving bank and, depending on the commerce environment and payment service , does so as part of an authorization request.
  • Step three:;The party thats acquiring the token initiates the routing process to transmit the token to the bank network for authorization.
  • Step four:;After authorization is complete, the token matches with the appropriate customer bank account while customer data remains secure in the tokenization systems digital vaults.
  • Step five:;The party issuing the token accepts or declines the transaction of funds, returns the token, and transmits its notice of authorization back to the bank.
  • Step six:;Upon notice of successful token and payment authorization, a new token transmits back to the merchant for use in future transactions.

    What Does A Token Look Like

    Pezold says there are two types of token formats: format preserving and non-format preserving.

    Format-preserving tokens maintain the look and feel of the original payment card data. For example:

    Payment Card Number: 4111 1111 1111 1111

    Format Preserving Token: 4111 8765 2345 1111

    Non-format preserving tokens dont resemble the original data and could include both alpha and numeric characters. For example:

    Payment Card Number: 4111 1111 1111 1111

    Non-format Preserving Token: 25c92e17-80f6-415f-9d65-7395a32u0223

    According to Pezold, most organizations use format preserving tokens to avoid causing validation issues with existing applications and business processes.

    What Type Of Business Can Benefit From Tokenization

    Credit Card Encryption OR Tokenization?

    A lot of people don’t understand what type of business can benefit from tokenization. A few obvious examples will come to mind, but the appeal is a lot broader than you initially may expect. It’s not just for businesses that do recurring billing. Let’s look at some examples.

    Obvious uses for tokenization:

    • Subscription based businesses

    Less obvious examples of businesses that see major benefits from tokenization:

    • Garbage company .
    • A contractor
    • Property rental company
    • Accountant
    • An e-commerce website where you want to allow returning customers to purchase without re-entering credit card details.

    The list can go on and on. Any company that will bill a customer more than once can benefit from tokenization.

    Using tokenization has many benefits beyond just the security aspects. It makes administration easier. You don’t need to wait for slow payers to make a payment. Instead you can do it yourself via the tokens, or even automate it so you don’t need to do anything.

    Challenges And Concerns Regarding Tokenization

    This is why we want them to tokenize. So when we talk about clients like this though, Carlo, there are a lot of clients we have that dont really want to tokenize. What is the concern that they have?

    The problem with this is really data loss or thats the real fear thats coming from these clients. I mean, you have a ton of information, sensitive information from the clients, the information about the orders, where theyre coming from-

    With the data, they dont really want to rock the boat here. Sometimes there are millions of dollars at stake here. One false move, and you could be losing a ton of sensitive data thats valuable to your business.

    Who Benefits From Credit Card Tokenization

    Everyone, really, except maybe for hackers.

    Lets start with consumers. Maybe data breaches are inevitable, but if one occurred at a merchant where you had used your card, tokenization would make it much less of a hassle. Because your card data was never stored by that merchant, only the token, you wouldn’t need to get a new card with a new number. You wouldn’t have to provide that new number everywhere you’re using the card for automated payments utilities, Netflix, Amazon, Uber, etc.

    For merchants, credit card issuers and payment networks, tokenization reduces fraud, which reduces the cost of doing business.
