We can see bar codes and trademarks on many commodities. In fact, many commodities have requirements for this. Many large supermarkets, or import and export trademarks, need not only trademarks, but also bar codes, so they often appear on a commodity at the same time, but their functions are not exactly the same.

According to my understanding of trademarks, trademarks and bar codes also have some similarities. First of all, they are not mandatory, but voluntary. Whether it's a trademark or a bar code, you can apply if you want, and you can apply if you don't. This is not necessarily mandatory. Of course, some places are mandatory. Such as medicine and tobacco, it is impossible without trademarks. This is mandatory.

The second similarity is that in some large supermarkets or e-commerce platforms, there may be requirements for trademarks and barcodes, because with these things, goods are not only easy to identify, but also reassuring in transactions. Who can rest assured of something without a brand?

But there is still a difference between the two. First, the object of recognition, the trademark is for people to see, and the bar code is for machines to see. People can know what brand it is at a glance, but the bar code has to be compiled by the computer, and everyone knows the other attributes of the trademark.

The second difference is that the agencies are different. Trademarks are handled by the Trademark Office, and barcodes are handled by the Article Coding Center. In addition, trademarks are loosely managed internationally, while bar codes and ean codes are unique internationally.
