Abstract

A radio frequency identification (RFID) tag includes a power supply, a RFID microchip, an enable unit, an adhesive unit, and a conducting unit. The adhesive unit is positioned on a bottom surface of the RFID tag. The conducting unit is secured to the bottom surface of the RFID tag through the adhesive unit. An end of the conducting unit is electronically connected to the power supply or the enable unit. Another end of the conducting unit is connected to the RFID microchip. The power supply or the enable unit switches on/off the RFID microchip through the conducting unit.

Claims

1. A radio frequency identification (RFID) tag, comprising:

a power supply;

a RFID microchip;

an enable unit;

an adhesive unit positioned on a bottom surface of the RFID tag; and

a conducting unit secured to the bottom surface of the RFID tag through the adhesive unit;

wherein an end of the conducting unit is electronically connected to the power supply or the enable unit;

another end of the conducting unit is connected to the RFID microchip;

the power supply or the enable unit switches on/off the RFID microchip through the conducting unit.

2. The RFID tag of claim 1, wherein the RFID microchip comprises a power terminal and an enable terminal, an end of the conducting unit is connected to the power supply, another end of the conducting unit is connected to the power terminal;

the enable terminal is connected to the enable unit.

3. The RFID tag of claim 1, wherein the RFID microchip comprises a power terminal and an enable terminal, an end of the conducting unit is connected to the enable unit, another end of the conducting unit is connected to the enable terminal;

the power terminal is connected to the power supply.

4. The RFID tag of claim 1, wherein the adhesive unit is an adhesive.

5. The RFID tag of claim 1, wherein the conducting unit is a metal wire or a carbon electrode.

6. An article-monitoring system for monitoring an article, comprising:

a reader card;

a radio frequency identification (RFID) tag, the RFID comprising;

a power supply;

a RFID microchip;

an enable unit;

an adhesive unit positioned on a bottom surface of the RFID tag, the RFID tag secured to the article through the adhesive unit; and

a conducting unit secured to the bottom surface of the RFID tag through the adhesive unit;

wherein an end of the conducting unit is electronically connected to the power supply or the enable unit;

another end of the conducting unit is connected to the RFID microchip;

the power supply or the enable unit switches on/off the RFID microchip through the conducting unit.

7. The article-monitoring system of claim 6, wherein the RFID microchip comprises a power terminal and an enable terminal, an end of the conducting unit is connected to the power supply, another end of the conducting unit is connected to the power terminal;

the enable terminal is connected to the enable unit.

8. The article-monitoring system of claim 6, wherein the RFID microchip comprises a power terminal and an enable terminal, an end of the conducting unit is connected to the enable unit, another end of the conducting unit is connected to the enable terminal;

the power terminal is connected to the power supply.

9. The article-monitoring system of claim 6, wherein the adhesive unit is adhesive.

10. The article-monitoring system of claim 6, wherein the conducting unit is a metal wire or a carbon electrode.

11. The article-monitoring system of claim 6, wherein the RFID tag further comprises a RF unit, the RF unit is connected to the RFID microchip, the card reader reads identifying information of the RFID tag through the RF unit.

12. The article-monitoring system of claim 11, wherein the RF unit is an antenna.

13. The article-monitoring system of claim 11, further comprising a terminal device, when the card reader gets the identifying information of the RFID tag in a predefined interval, the card reader determines the article is in a monitored area and sends the identifying information to the terminal device to monitor the article in a real time;

when the card reader can not obtain identifying information of the RFID tag in the predefined interval, the card reader determines the article is stolen or lost and sends a warning to the terminal device to remind a user.
