Abstract

A method for bulk encoding of RFID tags. The method may include printing a plurality of unencoded RFID labels, coupling each of the plurality of unencoded RFID labels to each of a plurality of products, packaging like products from the plurality of products coupled with the unencoded RFID labels together in a container, scanning the container holding the products with an RFID antenna, and encoding each of the unencoded RFID labels coupled to each of the plurality of like products in a container simultaneously with identical information for each container.

First claim

What is claimed is:

1. A method of bulk encoding radio frequency identification (RIFD) tags, comprising:
producing a plurality of unencoded RFID tags;
printing desired indicia on the plurality of unencoded RFID tags, the indicia corresponding to desired product or manufacturer information;
coupling each of the plurality of unencoded RFID tags to each of a plurality of products such that the unencoded RFID tags are placed into the products;
packaging identical products from the plurality products coupled with the unencoded RFID tags together in a container;
advancing the container along a length of a conveyor;
scanning the container holding the plurality of products with at least one RFID antenna;
adjusting a speed of the conveyor based on a type of the unencoded RFID tags or a number of products in the container for encoding;
encoding each of the unencoded RFID tags coupled to each of the plurality of products with comparable characteristics in the container simultaneously with identical information to create a plurality of encoded RFID tags; and
testing the plurality of encoded RFID tags within the container via bulk scanning so as to determine that all the encoded RFID tags within the container are encoded with data having identical information relating to the products and sorting the products such that only identical products are packaged in the container and nonconforming encoded RFID tags are removed for re-encoding or reworking.

2. The method of claim 1 , further comprising:
printing the plurality of unencoded RFID tags at a first location; and
transferring the plurality of unencoded RFID tags to a second location.

3. The method of claim 2 , wherein:
the first location is an RFID tag manufacturing location; and
the second location is a product manufacturer, a distributor, a reseller, or a retail location.

4. The method of claim 1 , wherein the products are apparel products.

5. The method of claim 1 , wherein the unencoded RFID tags are RFID labels.

6. The method of claim 1 , wherein the unencoded RFID tags are hard RFID tags.

7. The method of claim 1 , further comprising:
communicating information about the products within a container to the at least one RFID antenna such
that the information encoded by the at least one RFID antenna corresponds to the products within a particular container.

8. A system for encoding RFID tags in a container with uniform information, comprising:
a plurality of unencoded RFID tags,
a plurality of products;
a plurality of containers;
and at least one RFID antenna;
wherein each of the plurality of unencoded RFID tags are coupled to each of the plurality of products such that each of the plurality of products are similar in each of the plurality of containers, advance each of the plurality of containers along a length of a conveyor, adjust a speed of the conveyor based on a type of the plurality of unencoded RFID tags or a number of products in each container for encoding, and each of the plurality of unencoded RFID tags in each container is simultaneously encoded with identical data relating to the plurality of products placed in each of the plurality of containers by the at least one RFID antenna to create a plurality of encoded RFID tags,
a second RFID antenna arranged opposite to the at least one RFID antenna such that one of the plurality of containers can be disposed between the at least one RFID antenna and the second RFID antenna;
a quality control unit for testing the plurality of encoded RFID tags within each container of the plurality of containers for a uniform response such that the quality control unit is an interrogator antenna that tests each of the plurality of encoded tags for a uniform response; and
nonconforming encoded RFID tags are removed for re-encoding or reworking.

9. The system of claim 8 , further comprising:
a sorting mechanism for packaging sorting products such that each of the plurality of containers contains identical products.

10. The system of claim 8 , further comprising:
a conveyor for transporting the plurality of containers past the at least one RFID antenna.

11. The system of claim 10 , wherein the conveyor is adapted to transport the plurality of containers at a speed of between 0 feet per minute and 600 feet per minute.

12. The system of claim 8 , wherein the at least one RFID antenna is disposed at a distance of 1 foot to 5 feet from one of the plurality of containers.

13. The system of claim 8 , wherein each of the plurality of containers contains between 10 and 20 products.

14. The system of claim 8 , wherein the products are apparel or garments.

15. A method of bulk encoding RFID tags, comprising:
producing a plurality of unencoded RFID tags;
attaching each of the plurality of unencoded RFID tags to each of a plurality of products;
advancing products from the plurality products with the attached unencoded RFID tags along a length of a conveyor;
scanning each of the unencoded RFID tags attached to each of the plurality of products with at least one RFID antenna; and
adjusting a speed of the conveyor based on a type of the plurality of unencoded RFID tags or a number of products in a container for encoding,
encoding each of the unencoded RFID tags attached to each of the plurality of products with comparable characteristics with identical information sequentially one after another while on the length of the conveyor to create a plurality of encoded RFID tags;
printing desired indicia on the plurality of encoded RFID tags, the indicia corresponding to desired product or manufacturer information;
scanning the plurality of encoded RFID tags with a quality control unit and reserving nonconforming encoded RFID tags for re-encoding, reworking or removal; and
sorting the plurality of products such that only identical products are packaged in each container.

16. A system for encoding RFID tags with uniform information, comprising:
a plurality of unencoded RFID tags,
a plurality of products; and
at least one RFID antenna;
wherein each of the plurality of unencoded RFID tags are coupled to each of the plurality of products,
a sorting mechanism for products and containers to facilitate placing the plurality of products in corresponding containers,
advancing products from the plurality products with the attached unencoded RFID tags along a length of a conveyor;
adjusting a speed of the conveyor based on a type of the plurality of unencoded RFID tags or a number of products in the corresponding container for encoding,
each of the plurality of unencoded RFID tags is encoded one after another with identical data relating to the plurality of products by the at least one RFID antenna creating encoded RFID tags, and
testing the encoded RFID tags within each container via bulk scanning so as to determine that all the encoded RFID tags within each container are encoded with identical data relating to the products within the corresponding container;
identifying nonconforming encoded RFID tags; and
reserving the nonconforming encoded RFID tags for re-encoding, reworking, or removal.
