notes for "Auto-ID"

slide 1

smiliar to barcode, but read wireless

Institues/Companies

off

universal product code AKA barcode dev in '73, made for 25 years
barcode must be read manually

scenario: walk in shop; put chocoloate in jacket; walk out → paid; stock gets checked

slide 3

similar to alarm-tags - alarm if tag not deactived after paid
concept taken from technology from '40, tags on aircrafts (friend or foe)

tagging: ePC generated, unique code; smart-tag: microchip with antenna and small capacitor; sticked on can → becomes unique
reading: electro-magnetic field loads cap; enough energy for m.chip; m.chip sends ePC; internet or Lan translates ePC in usefull information (PML)

ePC: ePC similar to barcode (12 digits/ ~36 bits); but much bigger (96bits); OSN (object name service) translate code in internet-adress
PML: PML = physical markup language; parts, length, mass, ...; can describe in topdown, transport vehicle, containers, items

both could be saved on CDs/weekly (backup), if inet fails

may redefine the way things are made, bought and sold

Consumer: products that communicate: product may provide cooking inst. for microwave, supply-info to refrigator, fabric-care inst. to washing machine; shopping on-demand: food orderd autmatically as it runs out; increase human safety: medications warn of harmfull combinations; get info about product via PDA or cell phone @shop
Business: information about inventory: precise and detailed info on when, where & by whom an item was made; production/delivery on-demand: know when item leave factory and when sold, increase accuracy with which products made, shipped, delivered, and stocked → (leads to) enhanced costumer sevice.; saves billions, nowadays lost 'cause of lost, stolen, wasted products
Enviroment: waste reduction: smart produ gets reused throughout suplly & demand cycle, products may be moved back to manufacturer after use →; recycling: nowadays waste can't be identified, with auto-id it an be sorted and re-used easly

off

and other problems

tracking: everyone tracked via items, ie. pornography. but reader must near smart-tag. detailed information (via PML) restricted. solution destroy or throw away smart-tag
cheating: false smart tag could send other ePC-code. solution shops only accept ePC-codes in stock
expensive: still cost ~20 cents/tag, researches think dev may lead to costs less a penny/tag

thanx, questions?
