Abstract:
1. A method for authorization-dependent control of a contactless interface of a portable data carrier with contactless communication capability, the method comprising: receiving by the portable carrier, first authentication data corresponding to a user of the portable data carrier from an external device via a contact interface of the portable data carrier; performing, by the portable data carrier, an authentication operation on the first authentication data; logically deactivating, by the portable data carrier, in response to successful authentication of the first authentication data, the contactless interface of the portable data carrier, wherein the logical deactivation of the contactless interface of the portable data carrier includes: after logically deactivating the contactless interface of the portable data carrier, receiving, by the portable data carrier, second authentication data corresponding to the user of the portable data carrier from the external device via the contact interface of the portable data carrier; performing; by the portable data carrier, an authentication operation on the second authentication data; and logically activating, by the portable data carrier, in response to successful authentication of the second authentication data, the contactless interface of the portable data carrier, wherein the logical activation of the contactless interface of the portable data carrier includes deactivating the filtering function of the portable data carrier, wherein the filtering function is configured to cause the portable data carrier to accept only a command operable to activate the contactless interface.
