I am not sure of the pricing, but they are calling that the "pay-per-click" component of the model along with the holographic ad and the screen button. Per the case transcripts in February the latter are about $50 and $25, respectively, That's per month, per customer, per unit. For example, with six advertisers on a thousand machines that is $5.4+ million in annual sales. The catch is that pricing apparently is only for when they reach the ever elusive 1000 units mark and sales revenue is likely much lower currently.
