A method for enabling a chip card function of a chip card, the input of a first identifier being necessary for enabling the chip card function, and the chip card comprising a first contactless interface, comprising the following steps: - inputting a second identifier in a card reader, which has a second contactless interface; - transmitting a request for the remote check of the second identifier for agreement with the first identifier from the second contactless interface of the card reader to the first contactless interface of the chip card; - checking, by the chip card, as to whether the presently available number of input attempts for a correct input of the first identifier for enabling the chip card function exceeds a predefined minimum number and, if this is the case, carrying out the remote check, and, if this is not the case, carrying out the following steps: (i) transmitting a request for the input of a third identifier in the card reader from the first contactless interface of the chip card to the second contactless interface of the card reader; (ii) inputting the third identifier in the card reader; (iii) transmitting the third identifier from the second contactless interface of the card reader to the first contactless interface of the chip card; (iv) comparing, by the chip card, the third identifier to a fourth identifier stored in the chip card, and carrying out the remote check only when the comparison shows that the third identifier agrees with the fourth identifier, wherein the chip card function is enabled when the remote check shows that the second identifier agrees with the first identifier, and the number of the presently available input attempts is reduced when the second identifier does not agree with the first identifier. - inputting a second identifier in a card reader, which has a second contactless interface; - transmitting a request for the remote check of the second identifier for agreement with the first identifier from the second contactless interface of the card reader to the first contactless interface of the chip card; - checking, by the chip card, as to whether the presently available number of input attempts for a correct input of the first identifier for enabling the chip card function exceeds a predefined minimum number and, if this is the case, carrying out the remote check, and, if this is not the case, carrying out the following steps: (i) transmitting a request for the input of a third identifier in the card reader from the first contactless interface of the chip card to the second contactless interface of the card reader; (ii) inputting the third identifier in the card reader; (iii) transmitting the third identifier from the second contactless interface of the card reader to the first contactless interface of the chip card; (iv) comparing, by the chip card, the third identifier to a fourth identifier stored in the chip card, and carrying out the remote check only when the comparison shows that the third identifier agrees with the fourth identifier, wherein the chip card function is enabled when the remote check shows that the second identifier agrees with the first identifier, and the number of the presently available input attempts is reduced when the second identifier does not agree with the first identifier.
