Abstract

A pallet content identification mechanism is a small electronic device that is attached to a pallet. The pallet content identification mechanism reads RFID tags on the pallet using an RFID portal scanner, converts the RFID information into corresponding barcode information, and transmits the corresponding barcodes to a barcode-based inventory control system in a format that looks like output of a wireless barcode scanner. In this manner the pallet identification mechanism allows a user to benefit from RFID technology on the pallet while still using barcode technology in the barcode-based inventory control system.

Claims

1. An apparatus comprising:

at least one processor;

a radio frequency identification (RFID) scanner coupled to the at least one processor;

a display coupled to the at least one processor;

a memory coupled to the at least one processor;

an RFID to barcode conversion mechanism that receives RFID information from the RFID scanner for a plurality of products simultaneously present on an inventory control structure in proximity to the RFID scanner, converts the RFID information received from the RFID scanner into a corresponding plurality of barcodes, and that outputs the plurality of barcodes to the display in succession, with each barcode being displayed for a selected minimum time period.

2. The apparatus of claim 1 wherein the plurality of barcodes each comprise uniform price code (UPC) barcode information.

3. The apparatus of claim 1 further comprising a transmitter coupled to the processor that transmits the barcode information via wireless interface to a wireless receiver that is part of a barcode-based inventory control system in a format that looks like input from a wireless barcode scanner in the barcode-based inventory control system.

4. An inventory control structure comprising:

(A) a support structure that supports products for shipping; and

(B) a content identification mechanism attached to the support structure, the content identification mechanism comprising;

at least one processor;

a radio frequency identification (RFID) scanner coupled to the at least one processor;

a display coupled to the at least one processor;

a memory coupled to the at least one processor; and

an RFID to barcode conversion mechanism that receives RFID information from the RFID scanner for a plurality of products simultaneously present on the support structure, converts the RFID information received from the RFID scanner into a corresponding plurality of barcodes, and that outputs the plurality of barcodes to the display in succession, with each barcode being displayed for a selected minimum time period.

5. The inventory control structure of claim 4 wherein the corresponding barcode information comprises uniform price code (UPC) barcode information.

6. The inventory control structure of claim 4 further comprising a transmitter coupled to the processor that transmits the barcode information via wireless interface to a wireless receiver that is part of a barcode-based inventory control system in a format that looks like input from a wireless barcode scanner in the barcode-based inventory control system.

7. The inventory control structure of claim 4 wherein the support structure comprises a pallet.
