RFID error detection systems and methods

1. A retail RFID tag exclusion system, comprising:

a set of at least one RFID antennas positioned proximate a limited area within a retail shopping facility and configured to detect RFID tags within the limited area;

an RFID criteria database receiving and storing sets of RFID tag read criteria; and

an RFID evaluation control circuit implementing code stored on a memory and configured to:

access a first set of current tag read criteria associated with a current reading of a first RFID tag by the set of at least one RFID antennas;

access, through the RFID criteria database, multiple sets of previous tag read criteria;

access a set of at least one tag evaluation rules to evaluate detected RFID tags;

apply the set of tag evaluation rules and identify when a threshold number of the first set of current tag read criteria are each within corresponding criteria thresholds of a corresponding previous tag read criterion of a second set of previous tag read criteria; and

exclude the first RFID tag when the threshold number of the first set of current tag read criteria are within the corresponding criteria thresholds of the corresponding previous tag read criterion of the second set of previous tag read criteria.

2. The system of claim 1 , wherein the RFID evaluation control circuit is configured to:

identify a first set of items associated with a first person;

cause a listing of items comprising the first set of items to be presented to the first person;

receive a notification specified by the first person that a first item should not be included in the listing; and

cause a corresponding third set of tag read criteria associated with the first item to be added to the RFID criteria database.

3. The system of claim 2 , wherein the RFID evaluation control circuit in causing the listing of items to be presented to the first person is configured to cause a point-of-sale system to render the listing through a graphical user interface displayed on a display associated with the point-of-sale system.

4. The system of claim 2 , wherein the RFID evaluation control circuit is configured to identify when the first item is identified by a threshold number of persons as not to be included in the respective listings associated with the persons, and cause an audit notification to be generated directing an audit of a first product corresponding to the first item.

5. The system of claim 1 , wherein the RFID evaluation control circuit is configured to:

identify when a threshold number of a third set of previous tag read criteria have each been within corresponding criteria thresholds of a threshold number of other sets of tag read criteria; and

designate the third set of previous tag read criteria as an erroneous set of tag reads to be used to exclude subsequent sets of tag read criteria that have the threshold number of tag read criteria that each are within the corresponding criteria thresholds of the third set of previous tag reads.

6. The system of claim 1 , wherein the RFID evaluation control circuit is configured to:

identify a first set of items associated with a first customer based on an RFID tag read for each of the items of the first set of items, including the first RFID tag, and intended to be purchased by the first customer;

wherein the RFID evaluation control circuit in excluding the first RFID tag is configured to autonomously cause the first item to be excluded by a point-of-sale system from a purchase set of items to be purchased by the first customer.

7. The system of claim 1 , wherein the RFID evaluation control circuit is configured to:

identify, based on an audit performed at the retail shopping facility of items of a product associated with the first RFID tag, that a first item exclusively associated with a third set of previous tag read criteria is no longer present at the shopping facility; and

cause the third set of previous tag read criteria associated with the first item to be removed from the RFID criteria database.

8. The system of claim 1 , wherein the RFID evaluation control circuit is configured to:

identify that a threshold period of time has passed since a third set of previous tag read criteria was detected relative to the limited area; and

cause the third set of previous tag read criteria to be removed from the RFID criteria database.

9. The system of claim 1 , wherein the set of current tag read criteria does not include an identifier of the first RFID tag.

10. A method of excluding erroneous retail RFID tags, comprising:

accessing a first set of current tag read criteria associated with a current reading of a first RFID tag by a set of at least one RFID antennas;

accessing, through an RFID criteria database, multiple sets of previous tag read criteria;

accessing a set of at least one tag evaluation rules to evaluate detected RFID tags;

applying the set of tag evaluation rules and identifying when a threshold number of the first set of current tag read criteria are each within corresponding criteria thresholds of a corresponding previous tag read criterion of a second set of previous tag read criteria; and

excluding the first RFID tag when the threshold number of the first set of current tag read criteria are within the corresponding criteria thresholds of the corresponding previous tag read criterion of the second set of previous tag read criteria.

11. The method of claim 10 , further comprising:

identifying a first set of items associated with a first person;

causing a listing of items comprising the first set of items to be presented to the first person;

receiving a notification specified by the first person that a first item should not be included in the listing; and

causing a corresponding third set of tag read criteria associated with the first item to be added to the RFID criteria database.

12. The method of claim 11 , wherein the causing the listing of items to be presented to the first person comprises causing a point-of-sale system to render the listing through a graphical user interface displayed on a display associated with the point-of-sale system.

13. The method of claim 11 , further comprising:

identifying when the first item is identified by a threshold number of persons as not to be included in the respective listings associated with the persons; and

causing an audit notification to be generated directing an audit of a first product corresponding to the first item.

14. The method of claim 10 , further comprising:

identifying when a threshold number of a third set of previous tag read criteria have each been within corresponding criteria thresholds of a threshold number of other sets of tag read criteria; and

designating the third set of previous tag read criteria as an erroneous set of tag reads to be used to exclude subsequent sets of tag read criteria that have the threshold number of tag read criteria that each are within the corresponding criteria thresholds of the third set of previous tag reads.

15. The method of claim 10 , further comprising:

identifying a first set of items associated with a first customer based on an RFID tag read for each of the items of the first set of items, including the first RFID tag, and intended to be purchased by the first customer;

wherein the excluding the first RFID tag comprises autonomously causing the first item to be excluded by a point-of-sale system from a purchase set of items to be purchased by the first customer.

16. The method of claim 10 , further comprising:

identifying, based on an audit performed at the retail shopping facility of items of a product associated with the first RFID tag, that a first item exclusively associated with a third set of previous tag read criteria is no longer present at the shopping facility; and

causing the third set of previous tag read criteria associated with the first item to be removed from the RFID criteria database.

17. The method of claim 10 , further comprising:

identifying that a threshold period of time has passed since a third set of previous tag read criteria was detected relative to an area; and

causing the third set of previous tag read criteria to be removed from the RFID criteria database.

18. The method of claim 10 , wherein the set of current tag read criteria does not include an identifier of the first RFID tag.
