20130335794 | OPTICALLY WRITABLE HOLOGRAPHIC MEDIA - An optically writable holographic card, an optically writable holographic media, and a method of making the media are herein described. The card has a media region that includes an optically writable material. The optically writable material has an holographic embossment such that an holographic image is producible by the optically writable material. The media includes an holographically embossed first layer. An optically writable, optically readable second layer conforms to the embossment. The holographic image is generable by the second layer. The method includes producing an holographic embossment associated with an holographic image. An optically writable layer is conformed to the holographic embossment. The holographic image is viewable in response to illuminating the optically writable layer. The optically writable layer is optically readable. The optically writable material on the card may support optically written digital data and an optically written image, or an optically written image having embedded digital data. | 12-19-2013 |
20130175793 | IDENTITY DOCUMENT WITH SECURE IMAGE - An identification document and method of manufacturing the same is disclosed. Specifically, the identification document includes an image area in which both a base material of the identification document and a security material are present. One or more images are written into the image area such that reliefs are created in both the base material and the security material and also such that the image is a continuous image, even across transitions from the base material and the security material. | 07-11-2013 |
20130148178 | DIFFRACTIVE MOTION OSM AUTHENTICATOR - An identification document authenticator and method of operating the same is disclosed. Specifically, the authenticator is equipped with a light source that illuminates an identification document. Authentic identification documents may comprise one or more diffractive elements that, when illuminated, generate a unique image. The image is then viewable via a viewer provided on the authenticator. | 06-13-2013 |
20120000985 | LIGHT ENABLED RFID CARD - A radio frequency identification (RFID) card having an antenna configured to transmit data wirelessly to a remote receiver and an integrated circuit configured to transmit the data through the antenna to the remote receiver. The integrated circuit includes a transmitter section and a memory section. The memory section is configured to store the data. A power generating device is configured to supply power to the integrated circuit and a light-sensitive switch is interposed between one or more portions of the RFID card. The light-sensitive switch is configured to provide electrical coupling between the one or more portions of the RFID card when light is incident on the switch. | 01-05-2012 |
20110315769 | PORTABLE OPTICAL CARD READERS - A device for reading optical data cards. This device includes a shuttle mounted on shuttle tracks within the device housing. The shuttle is configured to move back and forth on the shuttle tracks driven by the shuttle motor. A card loader allows optical data cards to be positioned onto the shuttle. A CD optical read head mounted on optical read head tracks and driven by a optical head motor reads modified to read a single track of optical card data reads the optical card. A controller receives data from the read head and controls the movement of the shuttle and the optical head. | 12-29-2011 |

The optically writable material on the card may support optically written digital data and an optically written image, or an optically written image having embedded digital data. | 10-27-2011 |
20100027785 | DEVICE AND METHOD FOR SECURITY HANDSHAKING USING MIXED MEDIA - A method and device for private/public key encryption using optical media. A key pair is generated, and the public key pair is stored on the optical media. The media is scanned and the optical media characteristics are used to hash stored information with the private key. The hashed version of the private key is then stored on the optical media. A read/write unit may subsequently de-hash the private key for encryption of data files. | 02-04-2010 |
20090230199 | DIFFRACTIVE DATA STORAGE - An identification card and a method for formation of the card are disclosed. The identification card comprises an optical identification element formed upon a surface of the identification card and an optical stripe formed on the optical identification element and having at least a portion formed substantially from a single material. The single material is configured to have a diffractive pattern formed thereon by exposure to a laser. The diffractive pattern is capable of retaining information that is, for example, unique to a cardholder and being readable by a light source external to the identification card. | 09-17-2009 |
20090212902 | SYSTEM AND METHOD FOR AUTHORIZING LIMITED ACCESS - A system and method for securely controlling access to a designated location with a single card having a permanent data storage medium and a temporary data storage medium disposed on the card. Biometric information is acquired from a person and written on the permanent storage medium. A verification terminal acquires biometric information from a possessor of the card, such as random and multiple biometric information, and reads the same type of biometric information from the permanent storage medium of the card. Upon a favorable comparison of biometric information of the card and card possessor, authorization data is written on the card specifying limited access. The biometric information and the authorization data can be uploaded to a local database. The type of biometric information to be acquired from the card possessor and read from the card is accessed from the database. If the biometric information from both the card and the possessor match, and if access attempted by the card possessor is in accordance with the limits of the authorization data, access will be granted. | 08-27-2009 |
