Abstract

A system and method of identifying objects packaged in electrostatic discharge (ESD) protection packaging is disclosed. The system includes an ESD protection package and a radio frequency identification (RFID) tag. The RFID tag is affixed to the object prior to being inserted into the ESD protection packaging. A RFID interrogation device having a transmitter, an antenna and a receiver is used to interrogate the RFID tag and output the identification data to a display or to a computer. The method includes affixing an RFID tag to an object prior to placement in the ESD protection packaging, providing a RFID interrogation device including an antenna in proximity to the packaged object, and reading the data stored by the RFID tag for identifying the object.

Claims

1. A system for identification of packaged products, the system comprising:

a passive radio frequency identification (RFID) tag affixed to or associated with an object to be identified;

an electrostatic discharge (ESD) protection package; and

an RFID interrogation device;

wherein the object is enclosed in the ESD protection package, and the RFID interrogation device transmits at a low radio frequency to the object, and

wherein the ESD protection package is oriented such that a first side of an exterior of the ESD protection package is oriented proximal to an antenna of the RFID interrogation device, and a second side of the exterior of the ESD protection package, opposed to the first side of the ESD protection package, is subsequently oriented proximal to the antenna.

2. The system of claim 1, wherein the low radio frequency is between approximately 120 kHz and approximately 150 kHz.

3. The system of claim 2, wherein the low radio frequency is approximately 125 kHz or approximately 134 kHz.

4. The system of claim 1, wherein the RFID interrogation device comprises a transmitter, an antenna and a receiver.

5. The system of claim 4, wherein the antenna comprises two antennas, each of the two antennas operable to transmit and receive low frequency signals and disposed such that the packaged object is insertable between the two antennas.

6. The system of claim 5, wherein an antenna of the two antennas comprises a first antenna and a second antenna, the first antenna operable to transmit signals and the second antenna operable to receive signals.

7. The system of claim 1, wherein the RFID interrogation device has a data interface configured to communicate with a computer, a telecommunications network, a visual display, or a combination thereof.

8. The system of claim 1, wherein the RFID tag has a read-only memory, a read/write-once memory, or a read/write memory.

9. The system of claim 1, wherein the RFID tag is configured to transmit at a low frequency.

10. The system of claim 9, wherein the low radio frequency of the RFID interrogation device and the low radio frequency of the RFID tag are the same low radio frequency.

11. The system of claim 1, wherein the RFID tag is affixed to the object by gluing, clamping, clipping, or tying.

12. A method of identifying an object in an electrostatic discharge (ESD) protection package, the method comprising:

providing a passive radio frequency identification (RFID) tag operable to store at least identification data associated with the object;

attaching the RFID tag to or associating the RFID tag with the object;

inserting the object into the ESD protection package; and

orienting the ESD protection package such that a first side of an exterior of the ESD protection package is oriented proximal to an antenna of an RFID interrogation device, and a second side of the exterior of the ESD protection package, opposed to the first side of the ESD protection package, is subsequently oriented proximal to the antenna,

wherein the RFID tag is responsive to low radio frequencies.

13. The method of claim 12, further comprising:

providing the RFID interrogation device, the RFID interrogation device having a transmitter, the antenna and a receiver;

interrogating the packaged object; and

at least one of displaying object information or transferring the object information to a computer data base.

14. The method of claim 13, wherein the transfer of object information to the computer data base is by transmission over a network.

15. The method of claim 13, further comprising updating an object inventory file in the computer data base.
