Abstract

Various systems and methods of handling items such as files are disclosed, including systems and methods for polling RFID-tagged items while they are stored in storage areas.

Claims

1. A method of minimizing interactions between overlapping RFID tags, wherein the method comprises the step of intentionally staggering the location of RFID tags on consecutive items to which RFID tags are applied.

2. A method of minimizing interactions between overlapping RFID tags, wherein the method comprises the steps of:

(a) determining an order in which items are to be placed in a storage area; and

(b) intentionally staggering the location of RFID tags on consecutive items in the order.

3. A method of minimizing interactions between overlapping RFID tags, wherein the method comprises the steps of:

(a) applying RFID tags to items;

(b) providing information in a database that is indicative of the location of the RFID tag on the item; and

(c) using the information to select successive items for a storage area so that instances of overlapping RFID tags are minimized.
