Take card payments into the age of ecommerce with network tokenization

The Primary Account Numbers (PANs) embossed on cards are from a different time. Discover how network tokenization takes card payments into the online economy.

In the 1950s, shopping happened in person, in cash, every time. The credit card was invented so people could pay without carrying a wad of cash. As paying in plastic gained ground, card schemes needed a way to connect cards to the people using them at scale.

Thus the PAN was invented. From the mid-1960s, the slightly raised embossed numbers on payment cards became the perfect way to keep track of card payments.

Technology has come a long way since then. We now drive electric cars, have flat-screen TVs in almost every household, and conduct a large part of our lives online. Yet the PAN remained the main identifier for online and in-person card payments, leading to a rampant trade of credit card information and fraud.

Luckily, there’s a way to protect customers from online payments fraud. Network tokens are used by digital wallets like Apple Pay and Google Pay, and by major card schemes to create effortless and secure online payments experiences.

Read on to learn about network tokens and why they help you protect your customers and your business.

What is network tokenization?

Network tokenization is an automated process that replaces a 16-digit PAN with a non-sensitive reference called a network token. These network tokens are used to authorize online and recurring payments. 

When a customer chooses to save their card details, that business can request a network token for that card and use that for future payments. Since network tokens don’t expire, the token will remain valid even if the issuer replaces a card. This results in higher authorization rates.

Network tokens are created by card networks like Mastercard, Visa, American Express, and Discover.

How does network tokenization work?

A network token can be requested by a merchant, payment gateway, or payment processor. The requestor sends a PAN to the card scheme, which forwards the request to the issuer. The issuer approves the request, and the network issues the token.

Tokens are domain-locked, meaning the same token can only be used by the party that requested it. This means that stolen tokens will only get scammers so far, since a token cannot be used by a party other than its requestor. 

To add an extra layer of security to network tokens, card schemes issue a cryptogram each time a customer uses their saved card details to initiate a purchase. These cryptograms are effectively one-time-passwords that are contextual to the business, token, and purchase. They need to be used together with the token for that specific payment and are valid until they’re used or expire.

What are the benefits of network tokenization?

Network tokenization has many benefits for schemes, digital businesses, payment processors, and consumers alike. They are specifically designed to improve the security and experience of online and recurring payments. 

Higher authorization rates

A PAN might expire and be replaced when a new card is issued. Any online or recurrent payment done with the expired PAN will be declined. Customers often don’t have overview on all their online purchases and subscriptions, making it near-impossible to update their payment information everywhere. 

Network tokens don’t expire, even if the PAN is updated. As long as the token is used, the payment will be authorized, leading to higher authorization rates. We’ve seen an average uplift of 3% in authorization rates for businesses on our platform who use network tokenization.

This is especially valuable for businesses with an online subscription model, like streaming services. Adopting network tokenization will reduce transaction failures, retries, and customer service costs.

Increased security 

Network tokenization improves security by design. Because tokens and cryptograms are bound to their requestor, stolen tokens are useless to fraudsters. On top of that, customer initiated payments require a one-time use cryptogram. And since the actual PAN is stored securely by the payment partner or scheme, it becomes more difficult to steal the payment information.

Ensure PCI compliance 

Businesses that store PANs need to comply with the Payment Card Industry Data Security Standard (PCI DSS). Since network tokenization replaces the sensitive PAN with a non-sensitive token, tokens are out of the PCI scope. Even businesses that are PCI compliant can reduce their PCI scope by replacing some of their PANs with network tokens. 

Save on processing fees 

Some schemes, like Visa, might charge a fee for the management of issued tokens. They still charge lower fees for processing tokens than for processing PANs. By adopting network tokenization at scale, you’ll save on every transaction.

Experience more benefits of network tokenization with Adyen

We’re seeing a fast adoption of the technology with 2 billion active network tokens on our platform to date. As card networks and issuers are updating systems to start using network tokens, the technology is constantly evolving. 

To help businesses adopt network tokenization with minimal hiccups, businesses can leverage our Network Token Optimization as a part of our single platform solution. With Network Token Optimization, our platform dynamically decides whether to use a token or a PAN depending on the issuers authorization preference at that time. The decision is based on machine learning that’s trained with data from the world’s largest ecommerce and online businesses and constant testing.

The best part? Your business can start using network tokens and network tokenization optimization with the same integration you use for payments.
