Abstract:
An identifying card comprising:a first surface carrying human readable information relevant to an owner of the identifying card; and a second, opposed surface carrying encoded information being adapted for sensing by a sensing device and decoded by a computational processor, so as to provide information relevant to the owner in a human readable form, the encoded information comprising an array of dots applied to said second surface; wherein the encoded information comprises spatially distributed redundancy encoded data such that the information is encoded in a highly fault tolerant mannner and can be decoded by said processor despite a localized obliteration of the encoded information on the card.
