Abstract

Abstract A portable ID card verification apparatus is disclosed. The apparatus includes a housing defining an interior region supporting electrical circuitry including a processor. A two dimensional imaging assembly is at least partially enclosed within the housing. A display screen in electrically coupled to the imaging assembly. An upper surface of the housing supports a glass window on which an ID card is positioned for reading a dataform imprinted thereon. The dataform includes a compressed digitized representation of an attribute of the authorized card holder, such as a photograph of the card holder. The imaging assembly images and decodes the 2D dataform on the ID card and the processor in conjunction with display driver circuitry causes an image of the card holder's photograph to be displayed on the display screen.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 218 words
A portable verification apparatus for reading a dataform imprinted on an ID card, the dataform including an encoded, digitized representation of an attribute of an authorized user of the card, the apparatus comprising: a) a housing defining an interior region and supporting electronic circuitry including a processor; b) a substantially transparent window supported by the housing and being accessible from an exterior of the housing, the window providing a support surface upon which the ID card is placed, the card's dataform being visible through the window; c) an imaging assembly coupled to the electronic circuitry and including a camera assembly including a 2D photosensor array supported within the housing and an optics assembly spaced from the 2D photosensor array to focus an image of the dataform onto the 2D photosensor array; d) decoding circuitry for decoding the dataform imaged onto the photosensor array; e) a display screen electrically coupled to the electronic circuitry for displaying a decoded representation of the attribute of the authorized user of the card; and f) a mirror positioned between the substantially transparent window and the optics assembly and the optics assembly being positioned such that a longitudinal axis bisecting a field of view of the optics assembly is substantially parallel to a plane defined by a support surface of the substantially transparent window.
Claim 2
Dependent Claim 218 words
A portable verification apparatus for reading a dataform imprinted on an ID card, the dataform including an encoded, digitized representation of an attribute of an authorized user of the card, the apparatus comprising: a) a housing defining an interior region and supporting electronic circuitry including a processor; b) a substantially transparent window supported by the housing and being accessible from an exterior of the housing, the window providing a support surface upon which the ID card is placed, the card's dataform being visible through the window; c) an imaging assembly coupled to the electronic circuitry and including a camera assembly including a 2D photosensor array supported within the housing and an optics assembly spaced from the 2D photosensor array to focus an image of the dataform onto the 2D photosensor array; d) decoding circuitry for decoding the dataform imaged onto the photosensor array; e) a display screen electrically coupled to the electronic circuitry for displaying a decoded representation of the attribute of the authorized user of the card; and f) a mirror positioned between the substantially transparent window and the optics assembly and the optics assembly being positioned such that a longitudinal axis bisecting a field of view of the optics assembly is substantially parallel to a plane defined by a support surface of the substantially transparent window.
Claim 3
Dependent Claim 47 words
The verification apparatus of claim 1 wherein the 2D photosensor array and the optics assembly are supported by a movable support which is selectively movable along the longitudinal axis of the optics assembly and along two other axis which are both substantially normal to the longitudinal axis.
Claim 4
Dependent Claim 49 words
The verification apparatus of claim 1 wherein the optics assembly includes an outer housing which is threaded into a support shroud overlying the 2D photosensor array, the optics assembly being movable with respect to the photosensor array by rotating the optics assembly housing with respect to the support shroud.
Claim 5
Dependent Claim 105 words
The verification apparatus of claim 3 wherein the apparatus further includes focusing circuitry which displays the dataform on the display screen and illuminates a user visible indicator signal on the display screen indicating an sharper image if a user is rotating the optics assembly housing in a direction that improves a resolution of the image of the dataform onto the 2D photosensor array and illuminates a user visible indicator signal on the display screen indicated a worse image if a user is rotating the optics assembly housing in a direction that reduces the resolution of the image of the dataform onto the 2D photosensor array.
