RFID portals are designed for entrances, gates, doors, and hallways where a RFID reader is needed. The portal can actually scan RFID tags as they move into and out of an entrance. This is especially important in areas where tagged items are either entering or being removed from an area and need to be catalogued quickly.
How RFID Portals Work
RFID portals work similarly to other RFID technology. Like other readers, they have a transceiver and an antenna. The transceiver generates a weak radio signal that has a range of a few feet. This then activates a RFID tag passing within range when the signal is transmitted through the antenna.
The signal hits the transponder in the RFID tag, which then “wakes it up.” The transponder immediately responds afterward and sends the information stored within it to the reader. This process only takes a few milliseconds to complete.
With RFID portals, you can scan incoming and outgoing RFID tags associated with items. More specifically, portals are meant for applications where items are mobile and need to pass through a certain point.
RFID Portal Placement
When it comes to the placement of a RFID portal, you’ll want to place an antenna on either side and as close as possible to the path taken by pedestrians as is convenient. Additional antennas can also be placed above the doorway in order to track traffic.
