1. A vehicle speed monitor for monitoring speed of a moving vehicle, the vehicle speed monitor comprising an integrated circuit (IC) card, the IC card comprising:

  • an accelerometer being configured to measure instantaneous accelerations of the vehicle along three axes;

    a nonvolatile memory;

    a contact or contactless interface; and

    a processor being programmed to record the instantaneous accelerations measured by the accelerometer over time in the nonvolatile memory and to transmit, via the contact or contactless interface, at least one of (1) the recorded instantaneous accelerations and (2) scalar instantaneous speeds over time determined from the recorded instantaneous accelerations.
