When you eliminate the preconceived single card swipe process of the provisional DigEplayer trials...and condense it to a modular set back configuration.....you have a winner.

Flight length at that point is of no concern....with the card swipe at each unit they will have the ability if need be.. to sale content at different price points without steward activity being interrupted.

Still portable....however much more accommodating...

IMO..The pay back will be faster than the provisional system.
