Editing Worn device

A '''worn device''' is one that is ubiquitous and on the body all the time.  Examples include:

*[[wristwatch]] (usually just tell time but some have many more capabilities)
*[[ring]] (usually just jewelry but some include [[barcode scanner]])
*[[wallet]] or [[purse]]
*[[pocket]] (part of clothing and changed with clothing)
*[[key chain]] (usually in pocket, and carried with almost all clothing outside)
*[[walkman]] (always with a [[headset]])
*[[pager]] (typically with a one-line display, but some up to about 256 char)
*[[cell phone]] (often with a [[headset]])
*[[cordless phone]] (in some environments supporting [[PCS]] or other [[cordless protocol]], the [[headset]] is worn on the head or handset on wrist or belt - the [[base station]] is fixed in place in the environment and might support [[base station handoff]] which allows multiple carriers to cooperate to carry the same signal)

The term '''mobile device''' is often used to mean higher-tech worn devices, but there is no real difference in form factor, except that a mobile device is probably more likely to have a [[display]] screen capable of displaying more than one line, or an [[IP number]], whereas most of the above don't.  It is also more likely to have a bad user interface, contain [[tantallum]], and need to use both your eyes and both hands to make use of.  The more [[Consumerium Services]] can be deployed without these inconveniences, the more likely they will work.

The [[Consumerium buying signal]] will often be received by such a worn device.  Although it would ideally be available at the [[checkout counter]] or [[retail shelf]] or some [[kiosk]] in between (inside the retail location), it seems unlikely that this would be available for [[pilot]] or early phases, or in hostile retailers who wish to keep selling [[red-light product]]s without harassment.  Accordingly the worn device will have to be supported regardless, and since it serves so many other purposes in the [[healthy signal infrastructure]] it seems wise to assume that the [[healthy buying infrastructure]] will primarily rely on these devices, and not on any in-store deployment of specialized devices (which probably will be deployed only by those who specialized in [[green light]] products anyway, and wish to convince buyers that they are in fact much better than the alternatives not recommended).
