Patent ID: 8915436

Claim:
A system for data transmission, comprising: (a) at least one information carrier, comprising a flat plastic optical memory card which contains data stored in the form of two or more Fourier holograms, said Fourier holograms arranged on the card in a line at the same level, wherein the data stored in the form of two or more Fourier holograms comprises an ISO/IEC 16022 data matrix code, wherein at least one Fourier hologram comprises a plurality of Fourier holograms combined to form a larger hologram, each hologram of said plurality that form the larger combined hologram having identical data content encoded therein, wherein markings are applied to the information carrier which are used as a trigger signal for a read beam or a detector, wherein the larger combined Fourier hologram is larger than a read spot for reading a hologram; and (b) at least one reading device, said reading device comprising (i) a light source for producing a read beam, (ii) Fourier optics, (iii) a photodetector, and (iv) a guide device, wherein the guide device is configured to align the information carrier such that the carrier is positioned at a right angle in relation to a read beam and to the photodetector during the manual movement of the information carrier through the reading device during a reading operation, wherein said guide device and information carrier are configured such that the reading operation comprises reading at least one Fourier hologram sequentially after reading a first Fourier hologram, as the information carrier is manually moved through the reading device.
