Method and system for controlling the traffic flow through an RFID directional portal
First Claim
1. A system, comprising:
- a first motion sensor configured to sense 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;
a first radio frequency identification reader configured to be 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 further configured to read the first radio frequency identification tag;
a second motion sensor configured to sense a movement of a second object on the second side of the portal, the second object including a second radio frequency identification tag; and
a second radio frequency identification reader configured to be activated by the second motion sensor when the second motion sensor senses the movement of the second object on the second side of the portal, the second radio frequency identification reader further configured to read the second radio frequency identification tag, wherein the first motion sensor is further configured to deactivate the 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.

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.

19. A system, comprising:
-
a first sensing means 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; a first reading means being activated by the first sensing means when the first sensing means senses the movement of the first object on the first side of the portal, the first reading means for reading a first radio frequency identification tag of the first object; a second sensing means for sensing a movement of a second object on the second side of the portal; and a second reading means being activated by the second sensing means when the second sensing means senses the movement of the second object on the second side of the portal, the second reading means for reading a second radio frequency identification tag of the second object, wherein, when the first sensing means senses the movement of the first object on the first side of the portal, the second sensing means is deactivated for a predetermined period of time. - View Dependent Claims (20)
