  • Publication number: 20110004557
    Abstract: The method includes the steps of receiving at the PEAD first digital data representing the transaction request. The PEAD provides information to the user regarding an ability to approve the transaction request. When the transaction request is approved by the user, the PEAD receives second digital data representing the electronic service authorization token. A remote agent server may provide a bridge between the electronic transaction system and the PEAD. In another embodiment, the private key is stored on the portable device, encrypted. The decryption key is stored outside of the device, at a trusted 3rd party location. When the user attempts to make a signature the software sends a request for the decryption key, along with the user's password or pass phrase keyed in at the keyboard of the PDA, smart phone, or cell phone, to a server belonging to the trusted 3rd party.

  • Publication number: 20100289915
    Abstract: A TTR time of a reading apparatus can also be reduced by designing an apparatus to exhibit a certain timing relationship between a receipt of a trigger signal and/or more of image capture and decoding. An apparatus in one embodiment can be configured to continuously capture frames of image data prior to receipt of a trigger signal and can further be configured so that an output decoded message is decoded from a frame of image data having a capture initiation time of prior to the time of receipt of a trigger signal. An apparatus configured to output a decoded message from a frame of image data having a capture initiation time of prior to a time of receipt of a trigger signal can have a TTR time of less than a frame capture period of the apparatus.

  • Publication number: 20100276490
    Abstract: A scanning apparatus for decoding an encoded symbol character of a symbology includes a laser source operable to emit a beam along an axis and illuminate a target. The target includes an encoded symbol character. A focusing apparatus in optical communication with the laser source focuses the beam on the target at an object distance, and a detector receives light of varying intensities scattered from the encoded symbol character and converts the light into a first signal. A digitizer converts the first signal to a digital bit stream. The scanning apparatus further includes pre-stored information correlating a non-standard symbol pattern to a valid symbol character according to a standard definition of the symbology. The non-standard symbol pattern comprises a first number of elements that deviates from a second number of elements associated with the valid symbol character. A decoder receives the digital bit stream and utilizes the pre-stored information for decoding the signal.
