Does it say anywhere what hardware they used for training?

Long time reader but first time poster, had to share a story.

A decade ago was riding a bus in China, and they had a PSA type ad playing on the screens (paraphrased) "making sure when you're buying gold you distinguish investment (real) gold bars and decorative (fake) gold bars".

I thought "wow, how bad of a problem it must be to need such a PSA".
