Abstract
Embodiments presented herein describe an RFID system for detecting RFID tags in order to track inventory such as a pallet or individual packages. The RFID system includes at least one portal located in an inventory transport area. For example, the portal may be disposed at or near a dock door in a warehouse in order to detect when an RFID tag (and the corresponding inventory) passes through the door—e.g., when the inventory is loaded onto a truck. In one embodiment, the portal defines at least two RFID detection regions. For example, the portal may generate a RFID sensing region and a RFID read region. In one embodiment, a wide beam antenna generates the RFID sensing region while a narrow beam antenna generates the RFID read region.
