<p>The invention relates to a data carrier (1) having a security feature, said data carrier (1) including: - a data processor (10), - a memory (13) wherein a PIN is stored, and - a communication interface (14). The data carrier (1) is remarkable in that: - the data carrier further includes a random code generator (11) for obtaining a randomly generated code (X) and an output device (15) for outputting said randomly generated code (X) to a user, and - the data processor (10) is arranged to determine a first modified PIN from said PIN and said randomly generated code (X), wherein the communication interface is arranged for obtaining a second modified PIN entered by the user on an input terminal (2), and - the data processor (10) is further arranged to compare said first modified PIN and said second modified PIN.</p> |
