Editing Retail shelf

The '''retail shelf''' is where a customer first encounters the [[barcode]] and other aspects of the [[product label]] (like [[nutritional information]] and any [[standard label]] included on it like "[[kosher]]" or "[[dolphin free]]").

Because a customer moves past many such shelves rapidly, this is probably the worst possible point to ask them to use a [[worn device]], certainly not one that they must pull off a [[belt]] or out of a [[pocket]] to use, or which is not [[handsfree]].  For these reasons the [[headset]] is the best device for delivering any detailed information at this location.  This could be done by:

*[[barcode]] or [[RFID]] swiping by a [[worn device]] on the wrist which gets the cached [[Consumerium buying signal]] and plays it back into the headset;
*[[cordless callback]] initiating a call with [[cordless protocol]] and perhaps relying on [[PCS base station handoff]];
*[[cell phone]] callback with [[handsfree answer]]ing relying either on [[cell callback]] from a local server or on [[SMS message]] received handsfree and read into the headset by the phone itself, possibly via [[Python]] code.
*[[in-store radio]] which sends a [[barcode]] or [[RFID]] or [[NFC]] coded [[ID tag]] signal on a given frequency when a barcode is scanned in the store, and puts a [[Consumerium buying signal]] comment in the queue to read;

These would all work without taking one's hands off the product or [[shopping cart]], or one's eyes off the kids.

The shelf, cart or basket, and the [[checkout counter]] are the only guaranteed places in-store that the customer will encounter, so any [[Consumerium Service access]] should be optimized for these.  In [[friendly retail]] locations, e.g. the [[Big Carrot]] type store or [[local co-op]]s, it might be possible to augment the '''shelf''' itself, if the [[institutional buying criteria]] of that store are likely to closely match the [[individual buying criteria]] of the customer.  In that case, the [[Consumerium buying signal]]'s positive choice information becomes a definite [[price premium]] factor, and the whole store will probably be able to charge more for providing such complete profiles of what the customer is buying.
