MDES (Mastercard Digital Enablement Service) for Merchants is a tokenization and digitization solution for eCommerce merchants that uses a token, in combination with a transaction-specific cryptogram, to provide EMV-based security for card-on-file transactions. This delivers the security of network-tokenized transactions for credential-on-file use cases, enabling users to save tokenized credentials with merchants. Tokens replace PANs
