For one off payments you can exchange cardholder data for a single-use token that can be used as a payment instrument via the Tokenized Payment Flow
Card on File multi-use tokens can also be exchanged for single-use tokens. This can be useful if you wish to include CVV values in your payments as this data cannot be stored with Card on File.
