The objective of this project is to investigate the use of several technologies which, taken together in a complete system, provide the capability to track pharmaceutical products/services in both a retrospective and prospective manner. The approach is to design a system using bar codes, OCR, and electronic data transfer techniques to track product/services required by the Pharmaceutical Resources Branch (PRB) for production and control purposes. Recent advances in these fields suggest that products and documentation could be "tagged" and automatically tracked to a great extent, as the items traveled through their life cycle from generation to final receipt at NIH. The ability to track a product and know where its documentation is at any stage of its lifetime will facilitate the production and control required by the PRB.National Cancer Institute (NCI)
