Network tokenization is a type of payment tokenization where card details are replaced with secure tokens issued and managed through card networks such as Visa or Mastercard.
Instead of using the original primary account number (PAN) for a card transaction, the payment uses a network token. This token represents the card but can be limited to a specific merchant, device, channel, or transaction context.
Network tokenization is commonly used for digital payments, saved cards, mobile wallets, subscriptions, and card-on-file transactions.
When a card is tokenised through a card network, the original card details are replaced with a network token. The token can then be used for future payments without exposing the real card number to the merchant or other parties in the payment flow.
Network tokens can also be updated when card details change. For example, if a customer receives a replacement card after expiry or reissuing, the network token may continue to work without the customer manually updating their card details with the merchant.
Network tokenization can improve payment security and reduce friction for returning customers.
For merchants, network tokens can help:
Network tokenization is not the same as regular gateway or processor tokenization. Standard tokenization often happens within a specific provider’s environment, while network tokenization is connected to the card network and can support broader card lifecycle updates and payment continuity.
