PROBLEM TO BE SOLVED: To provide a simple, inexpensive security system which can monitor a product in each step from production to sale. SOLUTION: A printed security code assembly 2 for a carton or a container 4 of paper such as cardboard has a security code. The code stores switchable pieces of information 6, 8, 10 about each step from production to retail. The code is arranged at an optional position in the container 4, and the pieces of information 6, 8, 10 stored in the code can be read only by a code reader and changed over to be turned on/off. |
