Title
Systems and methods of using multiple RFID devices to implement in-store point-of-sale buy-zones and related articles of manufacture

Abstract
An RFID in-store point-of-sale system can include a first RFID tag reader with a first reader antenna that extends on a first substrate oriented in a first plane; and a second RFID tag reader with a second reader antenna that extends on a second substrate oriented in a second plane that intersects the first plane to form an offset angle between the first plane and the second plane that is about 45 degrees to about 135 degrees. A processor circuit can be operatively coupled to the first RFID tag reader and to the second RFID tag reader and can be configured to control the first RFID tag reader to transmit a signal from the first reader antenna into a buy-zone and is configured to detect movement of an RFID tag relative to the buy-zone based on a signal from the RFID tag that is detected by the first RFID tag reader or that is detected by the second RFID tag reader.
