“There’s always some sort of physical product that needs to be transported, and that’s what pneumatic tubes do,” said Matthew Kelly, a sales rep for his family’s company, Kelly Systems, which has been in the pneumatic tube business since 1904. He said the systems are becoming common in cannabis dispensaries.

“To move their product from the vault to the retail floor is a very controlled and policed system in the dispensaries, and you can either have somebody doing that or a system like this where it can’t be interrupted or tampered with,” Kelly said.
