Talk:Worn device

    From Consumerium development wiki R&D Wiki

    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 cards (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 products 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 PDAs or pagers or FM radios 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.
