CANTON, Mass., Jan. 15 -- Robotic Vision Systems Inc. has acquired Auto Image ID, a New Jersey-based manufacturer of digital imagers used in the reading of direct part marks and two-dimensional bar codes. Terms of the acquisition were not disclosed. The move is designed to strengthen RVSI's position in the 2-D direct part-marking segment of the automatic identification and data capture marketplace. Auto Image ID, which will operate within RVSI's Acuity CiMatrix Division, will have as its primary focus the penetration of new and existing markets for scanning of 2-D Data Matrix codes that are directly marked on various surfaces, including all types of metals, plastics, and silicon wafers. We believe this is the year that direct part marking moves into the mainstream of automatic identification, said Pat V. Costa, chairman and CEO of RVSI. The adoption of unit-level traceability is being driven by the need for higher quality, lower costs and control of the supply chain. We believe Data Matrix and other 2-D bar codes represent the future of tracking and tracing, and of helping boost productivity.
