You have been hired by a big grocery chain. They would like to target consumers with ads/specials as they shop in their store. Get together with your team and decide on a design concept that requires minimum data collections to maintain consumer privacy. How is the system going to work? What tools are you going to use to attract the consumer's attention? What data are you collecting? What is your justification for collecting each of the data items? How long are going to keep the data? Where is it going to be stored? etc
