Thanks for reaching out to us.
Both features support a "token", however these are two different technical processes. The feature you are probably looking for would be the "On-Files Sales Channel" - this is the 'standard token'.
The Scheme Token comes to use when e.g. a card is expired on a running subscription and the new card is automatically recognised on Issuer-side due to the Scheme Token.
I hope this helps you. If you have further questions do not hesitate to reach out us via Contact.
