A tokenization service offered by Mastercard that replaces a cardholder's sensitive account information, such as the 16-digit primary account number (PAN), with a unique digital identifier called a token. Tokenization is a process that helps secure online and mobile payments by replacing sensitive payment information with a unique digital token, a random string of numbers and letters with no value or meaning on its own.
How Tokenization Works
Tokenization transforms sensitive payment data into a token, a non-sensitive equivalent that can be used in transactions. The token is generated by the Mastercard Digital Enablement Service (MDES) and is specific to a particular transaction or set of transactions.
- Token Generation: The MDES creates a token for each transaction, ensuring that the original PAN is not exposed.
- Token Usage: The token is used in place of the PAN to process payments securely.
- Token Validity: Tokens are only valid for specific transactions, reducing the risk of fraud.
Applications of MDES
The MDES secures payments across various digital platforms, including mobile apps, online retailers, and other digital payment systems.
- Mobile Payments: MDES enables secure transactions through mobile wallets and contactless payments.
- E-commerce: Online retailers use MDES to protect customer payment information during online transactions.
- Digital Payment Platforms: Various digital payment platforms integrate MDES to enhance security and reduce fraud risks.
