Note that version 2.1 of the Other Card components does not enter any information other than necessary registration of Component Object Model (COM) objects in the registry. All of the registry entries defining an Other Card are now created by the Credit Card CPC. In addition, the Wallet's Credit Card CPC only permits installation of Other Card types that are unique. If a payment type already exists in the Payment Selector, installation of that type stops and an error is returned to the user.
Note Other Card components created with version 1.0 of the Microsoft Wallet Kit will not work in version 2.1 of the Wallet. You must rebuild them. For information, see the section "Sample Other Card Component."
