I would think that the bar code would be important to give an instant identification of the tank to be used in regard to things like certification. A tank could sit in a shop for years if infrequently used. When that tank gets returned, there is a very good chance that it is out of certification. That tank would then be sorted out to be hydroed and recertified. That is one of the benefits of the tank exchange system. The end user never has to worry about tank certification. The gas supplier is responsible for that.
