Network Tokenization

What is Network Tokenization?

Network tokenization is a security technology that replaces sensitive card details, such as the primary account number (PAN), with a unique digital identifier called a network token. These tokens are issued by card networks like Visa or Mastercard and are specific to a particular merchant and device.

Why It Matters

• It significantly reduces the risk of data breaches because the tokens are useless to attackers if stolen from a merchant’s database.

• Network tokens are automatically updated by the card networks when a card expires or is replaced, ensuring seamless recurring payments.

• It can lead to higher authorization rates as issuers have more confidence in the security of tokenized transactions.
