Player on computer without purchased composer?

I have 2 touchscreens at our tradeshow I am wanting to play intuface on. If I purchase intuiface Composer on my office computer, can I just purchase a player for each touchscreen down at the trade show? Or do I need Composer (purchased version) on both as well??

You can purchase player for your two other touchscreens at the tradeshow. That’s what players are for.
Composer is the authoring tool, Player is the runtime.
You can get all the information about Composer and Player here: Overview | This is how the parts fit together | Intuiface
