Abstract:
1. A chip card, comprising: multiple PIN objects, whereby each of the PIN objects is formed by: (i) an identifier which may be selected by a user, (ii) an incorrect entry counter associated with the identifier, and (iii) a use counter for an activation code associated with the identifier, whereby the activation codes are stored as part of an operating system of the chip card, and a first user function, which ensures that the chip card or a given function of the chip card has not been previously been subject to unauthorized use before the user of the chip card has selected the identifier, wherein: the first user function is formed by the use counters and the incorrect entry counters by the fact that the status of the first user function with regard to the one of the PIN objects is switched to a “used” status upon receiving the identifier of the one of the PIN objects, which is indicated by a status of the use counter of the one of the PIN objects, and when the one of the PIN objects is blocked the status of the first user function may be reset to the “first use” status upon receiving another of the activation codes associated with another of the PIN objects, thus replacing the blocked PIN object with the other of the PIN objects which has not been previously used, and each activation code may be used only once for resetting the first user function, and the use counters are not resettable.
