Patent ID: 10599968

Abstract:
An NFC tag shielding system for a multi-layer product of printed and/or non-printed layered material(s) includes a plurality of layers of printed and/or non-printed materials. The system includes a first on-metal NFC tag applied to a first layer of material of the plurality of layers and a second on-metal NFC tag applied to a second layer of material of the plurality of layers. The first and second on-metal NFC tags are aligned along an axis perpendicular to planes of the first and second layers of material. The system also includes an RF shielding layer disposed between the first and second on-metal NFC tags. The RF shielding layer is positioned along the axis and extends parallel to the first and second layers of material a distance covering at least a projected area of the larger of the first or second on-metal NFC tag. The RF shielding layer provides signal shielding between the NFC tags so that a user wishing to read the first NFC tag on the first layer of material will not unintentionally read the aligned second NFC tag on the second layer of material.
