| A '''barcode scanner''' or '''barcode reader''' is the device that reads a [[barcode]]. ''This will usually be required to trigger the [[Consumerium buying signal]] at the [[retail shelf]] or [[checkout counter]]. Supporting it is the most basic of our [[hardware requirements]] and [[software requirements]].''

| '''Barcode scanner''' devices exist in many forms, some of which are quite cheap, and others of which are quite small and portable. They are easily [[battery]] operated. The smallest are infrared contact devices. Those used in [[checkout counter]]s are high powered [[laser]] scanners, worn on the finger - the [[scanner ring]] that anyone can wear innocuously. ''This might provide an advantage in meeting certain [[performance requirements]].''
| | The [[mobile device code]] to integrate these with another body-[[worn device]], communications networks and the rest of the [[healthy buying infrastructure]] will typically have to run on [[Symbian]] or another [[mobile OS]]. [[Python]] support for these devices is the most likely integration path. |
