Abstract

A mobile information processing device includes a display driver for displaying a bar code, the bar code including a representation of a user'"'"'s acceptance of a price requested by a store for a selected item for purchase. The bar code may be one-dimensional or two-dimensional.

Claims

1. A mobile information processing device for use in a grocery store, the mobile information processing device comprising:

a housing in a form of a wristwatch;

a memory for storing a shopping list and an electronic route map of the grocery store, a private key of a shopper and a certificate;

a processor operatively coupled with the memory,

wherein the processor is configured to download the electronic route map of the grocery store and then, using this route map, rearrange shopping list items so that they track aisles in the grocery store, according to a set route; and

a user interface operatively coupled with a memory storing display driver, said user interface comprising;

a high resolution display screen comprising;

a touch-sensitive screen for entering a personal identification code of the user;

a scrolling-wheel input device;

the display driver driving the display screen configured to display;

purchase item information of a selected item;

a bar code encoding a payment message and the shopper'"'"'s certificate for the selected item for purchase; and

the price of the selected item together with an accept/reject icon that the shopper can manipulate with the touch-sensitive screen; and

a short-range transmitter for transmitting signals comprising the shopping list;

wherein the mobile information processing device is programmed to transmit signals that flag any items on the shopping list that are in close proximity to the short range transmitter by causing the flagged items to light up in order to alert the shopper to a location of the item; and

wherein the mobile information processing device is programmed to dynamically re-compute the shopping list to track the items according to a new route when the shopper deviates from the set route.

2. The mobile information processing device of claim 1 wherein the display driver displays the purchase item information as the bar code;

and wherein the bar code is two-dimensional.

3. The mobile information processing device of claim 1 wherein the bar code is one-dimensional.

4. The mobile information processing device of claim 1 wherein the bar code includes an encrypted e-signature.

5. The mobile information processing device of claim 1 wherein the user interface receives data from a user, the data comprising purchase information including a price of the selected item for purchase and a personal identification number.

6. The mobile information processing device of claim 1 comprising a belt clip for wearing on a belt.

7. The mobile information processing device of claim 1 comprising straps for wearing around a wrist.

8. The mobile information processing device of claim 1 wherein the display driver displays time.

9. The mobile information processing device of claim 1 wherein the user interface receives data from a user, the data comprising purchase information including a price of the selected item for purchase and a personal identification number;

and

wherein the processor converts the purchase information into a bar code.

10. The mobile information processing device of claim 1 wherein the short range transmitter moving out of range of the flagged items causes the flagged items to deactivate the lights.
