A security feature offered by Visa, Visa Token Service (VTS) replaces a cardholder's sensitive account information, such as the 16-digit primary account number (PAN), with a unique digital identifier called a token. This process, known as tokenization, enhances security for online and mobile payments by substituting sensitive payment details with a random string of numbers and letters. The token has no intrinsic value or meaning on its own and is used in place of the PAN to facilitate payment transactions. It is only valid for a specific transaction or set of transactions, thereby protecting the cardholder's sensitive payment information from potential compromise during the transaction process.
How Tokenization Works
Tokenization involves generating a unique token for each transaction, which acts as a stand-in for the PAN. This token is used by merchants and payment processors to complete the transaction without ever handling the actual account details. The tokenization process ensures that sensitive payment information is not exposed during the transaction, reducing the risk of data breaches.
- Token Generation: A unique token is created for each transaction, replacing the PAN.
- Transaction Processing: The token is used to process the payment, ensuring that the actual account details remain secure.
- Validation: The token is only valid for the specific transaction or set of transactions it was generated for, adding an extra layer of security.
