  • a hand-held sized housing;

    a slot for inserting a to-be-interrogated smart card;

    a storage medium stored with clock or power glitching timing information provided by a smart card issuer; and

    means for glitching clock or power in the smart card based upon said timing information, independent of any collaborating or communicating with any external computer system or equipment, to bypass authentication by a processor of the smart card via generating malfunction or confusion in the processor of the smart card to provide additional access thereinto;

    means for interrogating the glitched smart card to compare a response from the glitched smart card to interrogation so as to determine whether the smart card is issued by the issuer, wherein said device operates in a hand-held, in-situ, and free-standing manner.
