Editing Talk:Worn device

I wouldn't base so much emphasis on worn devices. Ok, if we can arrange for information to be delivered to a worn device, that's great, but maybe leveraging on existing devices (ie. PC at home) and infrastructure (ie. Internet for delivery) we will be getting to implementation a lot faster then with the "techno-gizmo of tomorrow"-approach.

:Fine but that is just a [[terminal]], of which the [[worn device]] is only one type.

Take for example the fact that many [[card]]s (some are [[evil]], used to AI analyze purchase patterns to optimize pricing and placement to reap the maximum profit) are swiped at the [[check-out]] cashier and the implementation effort (and cost) would be minimal if those cards conveyed an email address (or other drop-box distribution method) where the [[digital receipt]] of the purchases would be delivered to, naturally containing the [[GTIN]] codes of the [[product]]s purchased. 

:Only if the user isn't able to see the trace of records produced is this really [[evil]].  It might be a service to some people who have trouble budgeting or tracking purchases, or sticking to diets.  Or when people are paying bills for other people, like the [[mentally disabled]], maybe they have a right to see that they are not buying just cookies and ice cream but actual nutritious food... ?

This would be a form of [[Post check-out Consumerium]] that requires no additional hardware for the consumer, a simplification compared to [[Check-out Consumerium]] in which [[NFC]] (or [[Bluetooth]]) would be used to transmit the [[digital receipt]] to the consumers [[worn device]], most likely a [[cell phone]] or PDA

:Forget [[Bluetooth]], it just doesn't work, and trying to guess whether [[PDA]]s or [[pager]]s or [[FM radio]]s are going to do the eventual job is very difficult.  Do not forget that a working scanning headset FM radio can be picked for ONE DOLLAR at a dollar store.  That is the cheapest [[worn device]] possible...

Perhaps a [[Consumerium card]] could be arranged that only contains an email box where to send the [[digital receipt]]

:If you restrict yourself to email users, PDA users, even cell phone users, that's so few as to make this not ubiquitous.
