Since the metal cap plays a part in the RFID sealing device, the RFID shall malfunction once the bottle cap has been turned or opened before sale, so that the present RFID sealing device plays a function of safety identifier to the bottled liquid or food in addition. ## Claims ### Claim 1 A bottle sealing device, comprising: a radio frequency identification (RFID) strap mounted on a bottle, the strap having a top metal, a bottom metal, and a chip coupled between the top metal and the bottom metal, the RFID strap providing a radio frequency source and the top metal and bottom metal being physically isolated and electrically isolated with the chip between the top and bottom metals; a metal cap, configured on a top of a bottleneck of the bottle to seal the bottleneck and electrically coupled with the top metal, wherein the metal cap serves as a ground; and a metal strip having a first end and a second end, wherein the first end is electrically coupled to the bottom metal and the second end is an open-ended stub. ### Claim 2 (depends on 1) The bottle sealing device of claim 1, wherein said metal strip is configured to be affixed to a surface of the bottleneck. ### Claim 3 (depends on 2) The bottle sealing device of claim 2, further comprising: a metal tab coupled with the metal cap, the metal tab being configured to be extended downward from a bottom edge of the metal cap. ### Claim 4 (depends on 3) The bottle sealing device of claim 3, further comprising: a top metal piece configured for coupling the top metal with the metal tab. ### Claim 5 (depends on 4) The bottle sealing device of claim 4, further comprising: a bottom metal piece configured for coupling the bottom metal with the first end of the metal strip. ### Claim 6 (depends on 1) The bottle sealing device of claim 1, wherein the metal strip is substantially helical and substantially winds around the bottleneck. ### Claim 7 (depends on 6) The bottle sealing device of claim 6, wherein the metal strip has a substantially-constant, increasing, or decreasing slope as the metal strip winds down the bottleneck. ### Claim 8 (depends on 1) The bottle sealing device of claim 1, wherein a bottom of the metal strip is placed above a liquid level of a liquid contained in the bottle. ### Claim 9 (depends on 6) The bottle sealing device of claim 6, wherein the metal strip has a length of 8.8 to 9.1 cm, and an operating frequency of 900 to 910 MHz. ### Claim 10 A bottle sealing device, comprising: a radio frequency identification (RFID) strap mounted on a bottle, the strap having a top metal, a bottom metal, and a chip coupled between the top metal and the bottom metal, the RFID strap providing a radio frequency source and the top metal and bottom metal being physically isolated and electrically isolated with the chip between the top and bottom metals; a metal cap, covering an opening on a top of a bottleneck of the bottle to seal the bottleneck and electrically coupled with the top metal, wherein the metal cap serves as a ground and provides a ground potential to the RFID strap, and the ground potential of the RFID strap is only provided by the metal cap without additional grounded element; and a metal strip having a first end and a second end, wherein the first end is electrically coupled to the bottom metal and the second end is an open-ended stub. ### Claim 11 A bottle sealing device, comprising: a radio frequency identification (RFID) strap mounted on a bottle, the strap having a top metal, a bottom metal, and a chip coupled between the top metal and the bottom metal, the RFID strap providing a radio frequency source and the top metal and bottom metal being electrically isolated with the chip between the top and bottom metals; a metal cap, configured on a top of a bottleneck of the bottle to seal the bottleneck and electrically coupled with the top metal, wherein the metal cap serves as a ground; and a metal strip having a first end and a second end, wherein the first end is electrically coupled to the bottom metal and the second end is an open-ended stub.
