2/28/2006CAPSTONE Spring '06 CDR2 Project Description The system is made up of three different modules: Product Two different types of identification Passive RF ID Bar Code Shopping Cart Computing system for product identification and real time price update LCD, displaying product description and total price RF link to communicate with checkout counter Checkout Counter RF link to communicate with shopping cart Product Database

2/28/2006CAPSTONE Spring '06 CDR3 Purpose Facilitate people’s shopping Real time price update Audible (multilanguage) description (price, product name, etc.) Eliminate long/tedious lines Uploading final price to checkout counter, so that customer only needs to pay (no need to scan everything) Possible extension Advertisement opportunities Multilanguage Display
