Is there any transfer of personally identifiable information from the merchant to the InAcademia Service?

There is no need for the merchant to transfer any personally identifiable information to InAcademia in the validation request; InAcademia will simply utilise the home institution’s system to interpret the user’s academic affiliation and will complete the validation anonymously, returning a confirmation of affiliation, and a pseudonymised identifier to the merchant using what the OIDC protocol refers to as an ID token.
