Administration of medicines (especially guarantee of manufacture date and expiry date) is an important issue for patient safety in medical applications. Medical applications have a strong need for embedded tags on medical bottles to facilitate medicine management. However, 1D barcode cannot fulfill the required information capacity. The 2D barcode can support information capacity; however, it cannot meet the commercial level recognition rate when it is being used on curvature surfaces. On the

In this paper, a robust circular dot pattern code (CDPC) for tagging medical information on cylindrical and round type bottles for identification and management is proposed. Originally, CDPC was designed using the topological layout of dot code, and is well suited to recognizing tags in curvature environments. The different tagging mechanisms were presented in order to illustrate its importance on the administration of medicines. Experimental results show that the CDPC outperformed 2D barcode in its recognition rate on curvature including cylindrical and round shape.
