This could be actually experienced by the user in a great many ways. The Signal Wiki should have no bias as to how the signal is delivered. That's the main reason the language IS so abstract right now, actually.
- Web browser access to the Signal Wiki would be the default for in-home or in-office use, and might constitute the bulk of Consumerium Service access. However, it would not reach the actual point of purchase. This combined with Checkout Consumerium functionality, where you can grab the id's of products you just bought and take them out on you home or office computer.
- We could distribute data on what's in the store in book or leaflet form, even customized book form. You could for instance slide a frequent buyer card into a slot, and get a printed book with price premium information customized to you, or generic information like scores for at least some subset of highlighted products.
- This requires friendly retail although it might only be minimally friendly, i.e. having released price data for intershop comparison, bragging about its low prices, it's possible to calculate scores for every product.
- Coupons might tie in well to this kind of system.
- Data might get printed at the retail shelf display card or leaflet someday if some chain or region or nation decides to require it - the first step to Consumerium Country. This might be a way to positively market local food, for instance, and could work with tie-ins to the Slow Food people. This requires friendly retail.
- Customized and definitive buying advice, seen by the end user as a red/yellow/green traffic-type signal, or as a score easily translated into a price premium, or as a note in Simple English about issues with, or merits of, the product at the retail shelf.
- These would be expected to enable intrashop comparison of two products that the user is just about to buy, and it would be possible to get feedback on what you did buy, perhaps, if the checkout counter cooperates in the system.
The exact means of delivery probably depends on the way the system is made self-funding, what marketing tie-ins are possible, etc.. This is a task of the Consumerium Governance Organization and probably affects the Consumerium License.
