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 wireless transmitter 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 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 outputs the plurality of barcodes to the wireless transmitter in a format that looks like output of a wireless barcode scanner.

2. ) The apparatus of claim 1 wherein the corresponding barcode information comprises uniform price code (UPC) barcode information.

3. ) A method for inventory control, the method comprising the steps of:

(A) scanning a plurality of radio frequency identification (RFID) tags from a plurality of products simultaneously present on an inventory control structure using an RFID scanner;

(B) converting RFID information received from the RFID scanner into a plurality of barcodes;

(C) outputting the plurality of barcodes to a wireless transmitter in a format that looks like output of a wireless barcode scanner to a barcode-based inventory control system; and

(D) the barcode-based inventory control system receiving the plurality of barcodes from the wireless transmitter and processing the plurality of barcodes.

4. ) The method of claim 4 wherein each of the plurality of barcodes comprises a uniform product code (UPC) barcode.

5. ) 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 wireless transmitter 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 outputs the plurality of barcodes to the wireless transmitter in a format that looks like output of a wireless barcode scanner.

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

7. ) The inventory control structure of claim 5 wherein the support structure comprises a pallet.

8. ) An inventory control system comprising:

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

(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 wireless transmitter 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 outputs the plurality of barcodes to the wireless transmitter in a format that looks like output of a wireless barcode scanner; and

(C) a barcode-based inventory control system that receives the plurality of barcodes from the wireless transmitter and processes the plurality of barcodes.
