ABSTRACT:
An RFID tag and an RFID access card configured to reduce detuning effects from a typical RFID environment. The present invention provides an RFID tag that is specifically configured to reduce the detuning effects caused by initiating communication between an RFID tag and an RFID tag reader in the presence of materials such as metal, liquid, and the human body. In one embodiment, the present invention provides an RFID tag comprising an electronic circuit portion attached to a main antenna body portion, the main antenna body portion having two opposite side portions, which are substantially symmetrical with respect to one another, wherein each side portion extends outwardly to form a generally side-oriented v-shape.
