… it is important to rea­li­se the dif­fe­rence of digi­tal iden­ti­ty tran­sac­tions com­pared to pay­ments. An important con­side­ra­ti­on is that the value of a digi­tal iden­ti­ty tran­sac­tion is dif­fi­cult to deter­mi­ne becau­se of the con­text sen­si­ti­vi­ty: the value depends on what you can do with it. Com­mon busi­ness models in pay­ments app­ly a fixed and/​or ad valorum fee to tran­sac­tions. In this way, the­se busi­ness models app­ly some sort of value based pri­cing as mer­chants (or con­su­mers) are likely to accept a hig­her pri­ce for a tran­sac­tion, as the amount trans­fer­red is hig­her. With digi­tal iden­ti­ty the pri­cing might be depen­dent on the value the user and rely­ing par­ties perceive.
