Abstract: A method for individualizing a portable data carrier, in particular a chip card includes an end device that supplies data for configuring and/or updating one or more functions of the portable data carrier. The data are transmitted by the end device to the portable data carrier via a communication connection between the end device and the portable data carrier. A configurating and/or updating of the function or functions of the portable data carrier is effectuated by means of the data transmitted to the portable data carrier.

Abstract: The invention creates a data carrier, in particular chip card, in particular smart card, having a device for generating one-time passwords and having a display for displaying generated one-time passwords. Preferably the data carrier is a Eurocheque card or credit card with the integrated function of an electronic purse (cash card function) and the generated one-time password is a transaction number (TAN) for acknowledging a secure electronic payment transaction.

Abstract: A portable data carrier, in particular a chip card, comprises one or several sensors which are respectively arranged for detecting via the capture of measurement values a laying open of a surface of the portable data carrier as a detection event. It further comprises one or several output means for outputting signals perceptible by a user. The data carrier according to the invention is wherein it is arranged for outputting a signal via the one or more output means upon satisfaction of a detection criterion, the detection criterion being satisfied when the detection event is detected by at least a part of the sensors.
