Abstract

A method for shielding discarded or unwanted items provided with a Radio Frequency Identification (RFID) tag, comprises the following steps. First, a facility containing an inventory including a plurality of products each including a radio frequency identification (RFID) tag is provided. Then, the facility is provided with an RFID waste collection container defining a magnetic shielding enclosure for shielding and electromagnetically isolating the RFID tags when the products are disposed therein. Next, it is determined if one of the plurality of products is not wanted. Subsequently, the unwanted product is discarded by placing the unwanted product into the RFID waste collection container so that the RFID tag of the unwanted product does not interfere with ongoing activities in the facility by emitting errant signals.

Claims

1. A method for shielding discarded or unwanted products, said method comprising the steps of:

a) providing one of a retail facility, a wholesale facility and a manufacturing facility containing an inventory including a plurality of products each including a radio frequency identification (RFID) tag;

b) providing said facility with an RFID reader and an RFID waste collection container located in said facility adjacent to said RFID reader, said RFID waste collection container defining a magnetic shielding enclosure for shielding and electromagnetically isolating said RFID tags when said products being disposed therein;

c) determining if one of said plurality of products from said inventory is not wanted by a customer of said facility; and

d) discarding said unwanted product by placing said unwanted product from said inventory refused by the customer in said facility into said RFID waste collection container until said unwanted product collected and returned to said inventory so that said RFID tag of said unwanted product does not interfere with ongoing activities in said facility by emitting errant signals.

2. The method for shielding discarded or unwanted items as defined in claim 1, further comprising the step of collecting said unwanted product from said RFID waste collection container and returning said unwanted product to said inventory.

3. The method for shielding discarded or unwanted items as defined in claim 1, wherein said RFID waste collection container includes a shielding layer providing a substantially continuous electrical path surrounding said enclosure for electromagnetically isolating said RFID tags and blocking external electromagnetic fields.

4. The method for shielding discarded or unwanted items as defined in claim 1, wherein said RFID waste collection container includes a receptacle defining said magnetic shielding enclosure therewithin and having an opening providing access to said magnetic shielding enclosure, and a lid for selectively closing said opening of said receptacle.

5. The method for shielding discarded or unwanted items as defined in claim 1, wherein said facility is a retail store including a checkout provided with said RFID reader and said RFID waste collection container.

6. The method for shielding discarded or unwanted items as defined in claim 1, wherein said facility is one of manufacturing and wholesale facilities.

7. The method for shielding discarded or unwanted items as defined in claim 1, wherein each of said RFID tags stores data including data identifying one of said products associated with each of said RFID tags.
