Latest Patents

Tachi's latest patents include a two-dimensional code and a method of optically reading the same. This two-dimensional code consists of a matrix of cells formed with dark and light squares arranged in a specific pattern that carries optically readable binary-coded data. The design features at least two data regions defined within the data field of the matrix. One region retains a code represented by larger cells, while the other retains a code represented by smaller cells. This innovative approach allows for accurate reading of the codes under varying conditions.

Another significant patent is an object checking system capable of verifying objects irrespective of the type of reference data stored in an IC card. This system, particularly useful for signature checking, verifies each card carrier by comparing a signature entered on a tablet with reference data stored in the IC card. The terminal device sends the handwritten signature to the card and receives the check result, enabling verification regardless of the reference data type.
