Why Merchants Should Adopt Network Tokenization

Network tokenization helps merchants replace stored card numbers with payment tokens issued through the card networks. Instead of relying on a static PAN stored in a vault, the merchant can use a network token that stays connected to the card lifecycle.

That matters because expired cards, replaced cards, stolen-card events, and account updates all create friction in recurring and card-on-file payments. When the network token stays current, merchants can reduce failed payments, improve authorization performance, and lower exposure to raw card data.

What Network Tokenization Changes

Traditional tokenization replaces sensitive card data with a merchant or vault token. Network tokenization goes further: the card network participates in creating and maintaining the token, so the token can be used throughout more of the payment lifecycle.

For merchants, the business case is not only security. It is also payment continuity, authorization lift, lower lifecycle failure, and better handling of card updates.

Traditional Tokenization Process High-Level 

Currently, and before the Network Tokenization trend, to process a payment transaction, the minimum required fields are PAN, expiration date, amount, and sometimes zip code. Before processing any payment, there is a need to retrieve the actual PAN from the vault by the initially created token. This action is usually called “Exchange token for PAN.” PAN among other several fields wrapped in a message and sent over to the relevant issuer via a secured channel.

Traditional Transaction Flow

Traditionally, the card-holder needs to replace his credit card whenever it expires or is blocked as a result of fraud.

In the Network Tokenization era, to process a payment transaction requires just Network Token and amount. The card numbers, expiration dates, CVV, and other cardholders' information are updated by the card network automatically.

Network Tokenization Process High-Level

Network Tokenization has brought to the banking system and specifically the payments processing industry, a new standard. Network Token replaces the transactional Primary Account Number with a unique EMV® payment token, which was initially created by the card network. 

Network Tokenization is not just about transferring a token, instead of a primary account number, it is also used to make the actual issuer banks participate in the change that's happening to cross the board.

Transaction Network Token Flow

The main difference between Network Token and Non-Network Token is that Network Token is used throughout the entire transaction lifecycle instead of using the actual PAN, which is considered a traditional way

Until now, I've mentioned just the security and the payment processing side of Network Tokenization, but Network Tokenization solved some other issues in the logistics of dealing with credit cards. Today, we know something that is called account updater.

Finally, why do you need to adopt a Network Tokenization?

It's a service that is provided by the card networks like Visa, MasterCard, and a lot of others. It helps merchants to raise the authorization rate by keeping the payment methods updated in real-time, so expired cards, invalid account numbers, and CVV/CVC failures are no longer relevant.
