Bar code and two-dimensional code are applied to auto parts traceability.
It is now a variety of products traceability popular technology, fully applicable to various types of automotive parts. The past is the main auto parts labeled marker sequence number on the product, after the birth of the bar code is quickly applied to automobile parts identification, but too little information, easy to travel will not be fully spread. This problem until the birth of two-dimensional code technology was solved.
Two dimensional code is a checkerboard like 2D graphics, can be very small area content a large amount of information.
