A bit sequence is generated that produces a visible image on an optical card when written to the optical card as a series of etched and unetched states according to an optical-card writing protocol. For pixels distributed in two dimensions, an average intensity of the image in each pixel is determined. A bit arrangement is assigned to the pixel in accordance with the determined average intensity. For tracks distributed in one of the two dimensions across multiple of the pixels, bits defined by the pixel bit arrangements are mapped and distributed linearly within the track to a two-dimensional representation.

Methods and devices are provided for reading optical cards. A housing has a slot for slidably receiving an optical card. The optical card has physical tracks with an arrangement of physical pits to define on optically encoded biometric. A light detector is fixed in position relative to the housing. An optical train is also fixed in position relative to the housing and is configured to provide optical paths between the light detector and the optical card as the optical card is slid along the slot. A biometric sensor is provided. A processor is coupled with the light detector and with the biometric sensor. The processor has programming instructions to compare a biometric measured by the biometric sensor with the optically encoded biometric read from the optical card with the light detector.

An optical card is authenticated. The optical card has data stored on tracks in an optical storage area At least some of the data are encrypted. A character string is read optically from one of the tracks without decrypting any of the encrypted data. The character string is stored as a sequence of etched and unetched states within the track. The character string read from the track is verified to be identical to a predefined authentication string.

Systems and methods are provided for reading data encoded on an optical card as a series of binary pits formed within optical-card tracks separated by an average optical-card track pitch. A translator and a compact-disc laser head are provided. The compact-disc laser head reads data from a compact disc having data encoded as a series of binary pits formed within compact-disc tracks separated by an average compact-disc track pitch. The translator moves the optical card linearly relative to the compact-disc laser head in a direction of motion. The compact-disc laser head is oriented relative to the direction of motion to accommodate a difference between the average optical-card track pitch and the average compact-disc track pitch.
