Abstract

A transportable container is enabled with radio frequency identification (“RFID”) technologies to maintain automated inventory levels of those items that are inside the container. The inventory data is communicated via wireless methods, such as cellular or Wi-Fi, to a remote device such as enterprise resource planning (“ERP”) system. The ERP system may use the inventory data received from the remote device to automatically update appropriately and generate appropriate records (e.g., container inventory, restocking, invoicing, etc.). In some embodiments, automated RFID scans are triggered when the container is opened and subsequently closed. The container may include RF containment/screening to prevent inadvertent scanning of RFID tags outside of the container. The container may also include a location device to allow the location of the container to be readily determined.

Claims

1. A method for distributing a plurality of products, each product having an RFID tag, the method comprising:

a. providing a mobile RFID container, the container comprising;

a housing comprising a main body and a door, the main body and the door cooperating to define an interior compartment that is configured to carry the plurality of products, the door being movable relative to the main body between an open position to provide access to the interior compartment and a closed position to prevent access to the interior compartment;

a sensor configured to detect opening and closing of the door;

an RFID detector positioned in the housing, the RFID detector being configured to conduct an RFID scan of the interior compartment and collect scan data concerning the products contained within the compartment;

a controller coupled to the sensor and the at least RFID detector, the controller being configured to trigger an RFID scan via the RFID detector in response to the sensor detecting that the door has closed and to transmit scan data collected during the RFID scan to a remote device;

b. placing a plurality of products in the interior compartment of the mobile RFID container;

c. transporting the mobile RFID container to an end user;

d. conducting an RFID scan of the interior compartment of the mobile RFID container in response to sensing the opening and closing of the door following the transporting step; and

e. transmitting scan data collected via the RFID scan from the mobile RFID container to a remote device;

f. generating invoicing and/or credit data based on the scan data;

wherein the method further comprising transporting the mobile RFID container from the end user to a distribution center and restocking the container with products; and

wherein the step of restocking is based on scan data transmitted by the mobile RFID container prior to the RFID container reaching the distribution center.

2. The method of claim 1, wherein the invoicing and/or credit data is generated by the remote device.

3. The method of claim 1, further comprising wirelessly transmitting the scan data from the mobile RFID container.

4. The method of claim 1, further comprising conducting an RFID scan in response following the restocking step and transmitting inventory data collected via the RFID scan from the mobile RFID container to the remote device.

5. The method of claim 1, wherein the container comprises a GPS location device for generating location data indicative of the location of the mobile RFID container and the method further comprising transmitting location data from the mobile RFID container to the remote device.
