A passive or indirect link within a persona is when there is one piece of data connected indirectly to another piece of data. For example, let’s take a phone number that is linked from order A to order B. Order B is not my order, but rather another Kount customer's order. Order B is linked to Order C via an email address. Order C is my order. Orders A and C are linked in a passive manner, rather than directly through 1 piece of data, and will display as linked within the Persona Orders link on the Transaction Details pages for these orders.
It is important to pass a full contingent of linking data (full credit card number, email address, and device data). If, for instance, Merchant A were to only pass a masked value of a credit card number, within the graphical depiction above, both direct and passive linking ends at Merchant B.
