This is probably the most critical of the [[performance requirements]] - if it takes too long to do [[intershop comparison]], it just won't be done, and every second it takes to scan is one less second to do the lookup of the [[Consumerium buying signal]]. | ||
This is going to be a very very hard problem to solve. Overall the signal to the [[worn device]] can probably take no more than three seconds to receive - unless it is to be queued up for [[in-store radio]] or [[checkout counter]] presentation, which may require diligent consumers to return products to the shelves. If they do this in some way that we support directly, and if we or a store (!) pays them to do it, say in [[frequent buyer card]] type discounts, we can actually discover exactly what purchases were disabled by [[Consumerium buying signal]], and possibly (less likely) which ones were enabled by it. | This is going to be a very very hard problem to solve.
