Abstract

A method and system are provided to aid consumers having food allergies, or other dietary concerns. An RFID system is used to provide consumers with food product information. The food products are provided with smart tags. The tags containing information regarding the food product that is of interest to consumers with allergies or dietary concerns. A smart tag scanner is used to retrieve the food product information from the smart tags. The consumers scan a potential food product with the scanner and, based on the retrieved food product information, make an informed decision as to whether to purchase or consume the food product.

Claims

1. A method for providing consumers having food allergies, medical conditions, or dietary concerns with information about food products prior to purchasing or consuming such products, said method comprising:

providing food products with smart tags, the smart tags being associated with information regarding the food product that is of interest to consumers with food allergies, medical conditions, or dietary concerns;

scanning the food products prior to purchase or consumption with a smart tag scanner, the scanner configured to retrieve the food product information associated with the smart tags and to store the consumer'"'"'s specific personal profile;

providing the consumer'"'"'s specific personal profile containing data stored only on the smart tag scanner, the data regarding the consumer'"'"'s food allergies and medical conditions or medications taken by the consumer that are affected by food products or require particular dietary requirements;

conveying at least portions of the food product information to the consumer, including having the smart tag scanner alone compare the scanned food product information with the consumer specific profile and alerting the consumer with the scanner if any scanned food product is incompatible with any one of the consumer'"'"'s food allergies, medications, or medical conditions; and

wherein the smart tag scanner is a portable hand-held, unit that is personally owned and maintained in the possession of the consumer and brought by the consumer to the place of purchase or consumption of the food products, wherein the consumer'"'"'s specific food product profile is stored on a smart card scanned by the consumer'"'"'s scanner and wherein a commercial business providing the food products previously has given the scanner to the consumer.

2. The method as in claim 1, wherein the food product information contains the ingredients of the food product.

3. The method as in claim 1, wherein the food product information contains dietary information about the food product.

4. The method as in claim 1, wherein the scanner emits an auditory or visible alarm.

5. The method as in claim 1, wherein the scanners previously given to the consumers display the same type of non-consumer specific food product information to all consumers.

6. The method as in claim 1, wherein the consumers load consumer specific food product profiles into the scanners previously given to the consumers by the commercial business.

7. The method as in claim 1, wherein the scanners are carried in carts or baskets supplied by the commercial business.

8. The method as in claim 1, wherein the scanners are operated at a point of checkout.

9. The method as in claim 1, wherein the food product information includes a link to a remote database having information regarding the food product.

10. The method as in claim 9, wherein the scanner accesses the remote database and displays information therefrom to the consumer.

11. The method as in claim 10, wherein the remote database is an Internet site, the scanner being an Internet accessible device.

12. The method as in claim 11, wherein the Internet site is maintained by a manufacturer of the food product.

13. The method as in claim 1, wherein the smart tags are attached to packaging of the of the food product.

14. The method as in claim 1, wherein the smart tags are provided for a prepared meal prior to a consumer eating the meal, the food product information relating to the various food products of the meal.

15. The method as in claim 14, wherein the smart tags are provided by food service establishments on containers or trays served with the meal.

16. The method as in claim 1, wherein the smart tags are provided by food service establishments with menus.

17. A food product safety system for protecting consumers with food allergies and dietary concerns or requirements, said system comprising;

smart tags associated with food product information for particular foods, said food product information being of the type required by consumers with food allergies or dietary concerns related to medical conditions or medications taken by the consumer, said smart tags attachable to their respective food products; and

at least one smart tag scanner accessible to a consumer at a point of sale of the food products, said scanner being a portable hand-held unit of an individual consumer that is maintained in the possession of the consumer and brought by the consumer to the place of purchase or consumption of the food products and wherein said scanner is configured to read the consumer'"'"'s specific profile stored on a consumer specific smart card, said scanner configured to retrieve said food product information associated with said smart tags and compare the scanned food product information with a consumer specific profile storable only on said scanner from said consumer specific smart card controlled only by the consumer, the smart tag scanner being configured so as to preclude access to the consumer specific profile by any device other than the said scanner, the profile containing data regarding the consumer'"'"'s food allergies and medical conditions or medications taken by the consumer that are affected by food products or require particular dietary requirements, and the scanner being configured to alert the consumer if any scanned food product is incompatible with any one of the consumer'"'"'s food allergies, medications, or medical conditions.

18. The system as in claim 17, wherein said food product information comprises ingredients of the food product.

19. The system as in claim 17, wherein said food product information contains dietary information about the food product.

20. The system as in claim 17, wherein said scanner comprises at least one of an auditory and visible alarm.

21. The system as in claim 17, wherein said scanner is disposed in a cart or basket at a commercial business selling the food products to consumers.

22. The system as in claim 17, wherein said scanner is disposed at a point of checkout at a commercial business selling the food products to consumers.

23. The system as in claim 17, wherein said food product information comprises a link to a remote database having information regarding the food product.

24. The system as in claim 23, wherein said remote database is an Internet site, said scanner being an Internet accessible device.
