1. A device for reading book data, the device comprising:
- a housing including first and second housing sections connected by a hinge;
a flexible display positioned in the housing to extend from the first housing section to the second housing section over the hinge so as to be of approximately equal width to the housing, the flexible display configured to flexibly fold about the hinge;
a slot for receiving a card having visible content printed thereon, the card further having the book data encoded on the surface of the card as an array of dots, the array of dots being printed on the surface in ink substantially invisible to an average unaided human eye and being printed on the surface independently of the visible content printed on the surface;
a detector for optically detecting the array of dots across the surface of the card received in the slot and for outputting a first signal representative thereof;
a decoder interconnected to said detector for receiving and decoding said first signal to produce a display signal corresponding to the first signal;
wherein the display signal causes text or images corresponding to the book data to be displayed on said flexible display.

Abstract
A system is disclosed for reading data encoded as a series of invisible dots carried on a substrate. The system has a detector that detects the dots on the substrate and outputs a first signal; a decoder interconnected to the detector that decodes the first signal to produce an output signal; and an output device interconnected to the processor that receives the output signal and creates a corresponding human readable output. The dots may be infrared absorbing and the encoding can include Reed-Solomon encoding of the prerecorded audio. The system can include a wand-like arm having a slot through which the photograph is inserted.
