A system of changing the PIN associated with a smart card is described. A user can initiate the PIN change using a personal unwired smart card reader, rather than using a system, such as an ATM machine. The smart card reader, loaded with the smart card provides a cryptogram code, which can contain the user's requested new PIN or it can be provided to the issuer via alternative methods. Via various methods the cryptogram code is delivered to the card issuer's PIN change management system, including the user transposing the code from smart card reader screen to the card issuer's web site or audio DTMF transmission from the smart card reader speaker to the card issuer IVR system. Returned from the issuer, via a similar path, will be a command code that when processed by the smart card reader will result in a PIN change on the smart card. |
