Abstract
A wristband has a flexible elongated body with an open state in which the wristband is capable of being positioned in a planar configuration and a closed state in which the wristband is wrapped in a loop. An RFID circuit is supported by the body and is positioned on the body such that the RFID circuit is configured to be included in the loop when the wristband is in the closed state. The RFID circuit includes an antenna and one or more lines of weakness in the antenna. The one or more lines of weakness define tearable antenna segments that are removeable to change a length of the antenna of the RFID circuit.
Claims21
A device, comprising:
- a wristband having a flexible elongated body, the wristband having an open state in which the wristband is capable of being positioned in a planar configuration and having a closed state in which the wristband is wrapped in a loop such that a first end of the wristband overlaps a second end of the wristband and is fixed to the body;
- an RFID circuit supported by the elongated body of the wristband, the RFID circuit being positioned on the body such that the RFID circuit is configured to be included in the loop when the wristband is in the closed state, the RFID circuit including an antenna;
- and
- a line of weakness in the antenna, the line of weakness defines a tearable antenna segment that is removeable to change a length of the antenna.
A method, comprising:
- supporting an RFID circuit on an elongated flexible body of a wristband, the wristband having an open state in which the wristband is capable of being positioned in a planar configuration and having a closed state in which the wristband is wrapped in a loop such that a first end of the wristband overlaps a second end of the wristband and is fixed to the body, the RFID circuit having an antenna and being positioned on the body such that the RFID circuit is configured to be included in the loop when the wristband is in the closed state;
- and
- forming one or more lines of weakness comprising in the antenna to define tearable antenna segments that are removeable to change a length of the antenna.
The method of claim 19, wherein forming the one or more lines of weakness comprises forming a plurality of lines of weakness, each of the plurality of antenna segments extend over two percent to twenty-five percent of the length of the elongated body.
