14. An RFID wristband comprising;
-
a substrate;
an antenna portion of the substrate;
a strap on the substrate; and
a fold section on the substrate;
wherein the fold section contains an adhesive layer and wherein when the fold section is folded together with the adhesive layer at least one capacitor is created which sets the RF response of the RFID circuit, wherein the fold section has hole that the strap portion fits into such that adhesive layer of the fold section can hold the strap in place. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
