1. A handheld electronic smart card terminal, comprising:

  • a smart card reader for receiving and communicating with a smart card having smart card data stored thereon, said smart card comprising a cryptographic engine and said smart card data comprising a smart card secret;

    a token personality logic programmed based on the smart card data as a token device personality for offering the functionality of a strong authentication token, subsequent to insertion of the smart card in said smart card reader, wherein said smart card terminal obtains a secret device key from said smart card when received by said smart card reader by submitting to the smart card an input value for processing by the cryptographic engine using said smart card secret to derive the secret device key; and

    a communications mechanism for communicating authentication data derived from said token device personality to a user for transmission to an application provided by a service provider;

    wherein said smart card terminal is adapted to work at least in a non-connected mode; and

    wherein said smart card terminal further supports at least one of (i.) a security paradigm including at least a challenge response and a security paradigm including dynamic passwords based on at least a challenge input by the user and an event or (ii.) a security paradigm including dynamic signatures based on at least transaction data input by the user and an event.
