The Identity and Information section is a discussion about how one's self and information interplay in a time when information is powerful but we still want privacy.
The Interaction and Interface section allows for the user to contemplate the design of the technology just viewed, and how these forces were developed with or without the user in mind.
The Implications section lets the creators of scenarios forecast the next step in the technology they have created and discuss the social and cultural implications contained therein.

IDENTITY AND INFORMATION
Certainly grocery stores will be able to benefit from the information each shopper provides through the interface, such as preferred foods and allergies. Corporations with large databases will also try to gain access to this information in order to sell customers to other stores. Preferably, this information will be accessible only to the user when he or she enters a personal ID card (like a credit card) which will have all of their personal information stored on it. That way, when they remove their cards, their information goes with it and not to the stores or corporations.

INTERFACE/INTERACTIVITY
Tim interacts with the grocery agent to see what the specials of the day are. He also goes to the register to pay for his groceries. There he interacts with the robot grocery clerk.
This interaction helps Tim by showing him what items are on sale so that he can take advantage of the savings. The interaction with the robot enables Tim to quickly pay for his groceries and be on his way. +

The design of the store, including only robotic employees, may be somewhat awkward for anyone who prefers human interaction, but the use of robots allows humans to pursue other interests. The grocery agent could allow customers to put items into their carts without actually scanning them in an attempt to shoplift these items. But the robotic cashier compares the items in the cart to the store's price database to prevent theft.+

The technology and interaction are advantageous to the customer because they allow him to navigate throughout the store without confusion and quickly pay for his products.
By using the Grocery Manager, the character is able to access valuable information about the store and its products. For example, the character can have the agent monitor for certain ingredients that he may dislike or be allergic to. +

Also, he can use the agent to find out about daily specials on groceries. The agent also keeps track of the total amount spend so the character can better manage his budget.

IMPLICATIONS
This device justifies the premise that future grocery stores will not have a great effect on life in the future other than to make grocery shopping a more enjoyable and entertaining experience.
The consequences of technology like the "Grocery Manager" should make shopping more pleasant and hassle-free. One negative aspect which will need to be dealt with is the fact that people will be able to put items into their carts without actually scanning them into the grocery agent and, consequently, shoplift these items. +

Perhaps the best way to prevent this will be to have a magnetic strip placed on each item that will be scanned for when the user proceeds to the check-out.
The next step for this device would be to allow it to scan users' thumbprints in order to gain personal information about them (i.e.- their allergies, preferences, dislikes, etc.) as well as being able to simply deduct the final cost from their bank accounts by this form of identification.
