Two-dimensional code is one of the commodity coding methods, which can express information in both horizontal and vertical directions at the same time, so it can express a lot of information in a small area. Of course, it has broad application prospects, but it has not yet started in China. However, two-dimensional code and trademark are two different things, and there is no problem of squatting on two-dimensional code trademarks waiting for value-added, just as there is no correlation between commodity barcodes and trademark registration now.
