Abstract
A portable data carrier () comprising a contact pad () according to ISO 7816-2 as a physical interface for communication has a contactless interface device () for communication with an end device according to a contactless communication protocol via a preset activated contact assignment of the contact pad (), and at least one contact interface device () for communication according to a contact-type communication protocol via a further activated contact assignment of the contact pad (). In an initialization phase of the data carrier () a control device () activates a second contact interface device (), besides an already activated contact interface device (), only when the former does not use a contact assignment of the contact pad () that collides with the contact assignment of the contactless interface device (). The contactless interface device () is activated as a second interface device if the preset contact assignment of the contactless communication protocol does not collide with the contact assignment of the already activated contact interface device ().
