ABSTRACT:
A data carrier (1) which can be operated in a contact-bound mode and in a contactless mode and a circuit (2) for such a data carrier (1) has contact-bound interface means (3), contactless interface means (4), data processing means (22) and data transfer means (27) by which data received when the contact-bound mode is activated and when the contactless mode is activated can be transferred from the respective interface means (3, 4) to the data processing means (22), the data transfer means (27) being constructed to perform a logic OR function and, in conformity with this construction, when simultaneously data are received by the contact-bound interface means (3) and by the contactless interface means (4) to transfer said simultaneously received data to the data processing means (22).
