  • Patent number: 6015092
    Abstract: A smart card reader includes a smart card holder that is mounted to a PCMCIA card at a ninety-degree angle. The upstanding position of the smart card holder makes it easier for users to insert smart cards into it. Moreover, the position of the smart card holder enables connectors for cellular telephones, modems, network cards and the like to be connected in an adjacent PCMCIA slot without interfering with the operation of the smart card reader. Moreover, the provision of a separate smart card holder frees space within the PCMCIA card for housing a modem or other device performing electrical functions. In this way, a single smart card reader provides two or more separate functions, neither of which interferes physically with adjacent PCMCIA cards. As such, electronics for cellular telephones, modems, network connections and the like may be incorporated into the PCMCIA portion of the reader with connectors for these applications being on the trailing end of a smart card reader's PCMCIA card.

  • Patent number: 5854891
    Abstract: A security device for operating protected programs or data, or other functions performed by or within computers, the security device having both hardware and software keys and a reader for accepting smart cards. The smart card reader communicates with a control module having segmented non-volatile memory. Data from plural smart cards is entered into segmented NVM through the smart card reader. Each segment of segmented NVM creates a virtual token essentially duplicating enabling ability of the corresponding smart card or token. The control module has processing and memory means for encrypting and decrypting commands and recognizing encrypted passwords. The control module also has a plurality of interface apparatuses for enabling communicable connection to computers. When one or more virtual tokens is created by transfer of data from a smart card or cards, the smart card may be safely stored or discarded.
