The sports venue idea with the 150 touchless technology is a winner.
Everyone has been indoctrinated these days to sue for all things having to do with injury sustained at someone else's property. Here in the northeastern US a precedent has recently been set. A couple was able to collect a settlement from injuries sustained from an accident attributed to the the state for having not plowed the road of snow even though they were actively plowing and just had not gotten back to that spot. The cause for liability? The state had the 'capability'. See a parallel here? Owners and managers of high capacity occupancy sports venues will in time be considered as having the 'capability' of having screened at the very least the passage tickets with a hybrid mechanized scanners incorporating imsc's touchless etd technology combined with optical bar-code for rapid scan venue entry. The venue owners that neglected to deploy the 'capability' will be regarded as negligent thus opening themselves to lawsuits.
