METHOD AND SYSTEM FOR CONTROLLING THE TRAFFIC FLOW THROUGH AN RFID DIRECTIONAL PORTAL
First Claim
1. A system, comprising:
- a first motion sensor for sensing a movement of a first object on a first side of a portal, the portal comprising the first side and a second side, the first object including a first radio frequency identification tag; and
a first radio frequency identification reader for being activated by the first motion sensor when the first motion sensor senses the movement of the first object on the first side of the portal, the first radio frequency identification reader for reading the first radio frequency identification tag, wherein the first motion sensor deactivates a second motion sensor for a predetermined period of time when the first motion sensor senses the movement of the first object on the first side of the portal, wherein the second motion sensor is for sensing a movement of a second object on the second side of the portal, the second object including a second radio frequency identification tag.

Abstract
A system having a first motion sensor configured to sense movement of an object on a first side of a portal, the object including an RFID tag, a first RFID reader being activated by the first motion sensor when the first motion sensor senses movement of the object, the first RFID reader reading the RFID tag, a second motion sensor configured to sense movement of the object on a second side of the portal and a second RFID reader being activated by the second motion sensor when the second motion sensor senses movement of the object, the second RFID reader reading the RFID tag, wherein, when one of the first and second motion sensors sense movement of the object, the other one of the first and second motion sensors is deactivated for a predetermined period of time.

11. A method, comprising:
-
sensing, by a first motion sensor, a movement of a first object on a first side of a portal, the portal comprising the first side and a second side, the first object including a first radio frequency identification tag; and activating, via the motion sensor, a first radio frequency identification reader when the first motion sensor senses the movement of the first object on the first side of the portal, the first radio frequency identification reader for reading the first radio frequency identification tag, wherein the first motion sensor deactivates a second motion sensor for a predetermined period of time when the first motion sensor senses the movement of the first object on the first side of the portal, wherein the second motion sensor is for sensing a movement of a second object on the second side of the portal, the second object including a second radio frequency identification tag. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
