RF proximity financial transaction card having metallic foil layer(s)
First Claim
1. An RF proximity financial transaction card, comprising:
- a plastic inlay having first and second substantially planar surfaces bounded by a continuous peripheral edge;
an integrated circuit carried by said inlay storing card-specific data;
an antenna carried by said inlay that is operatively connected to said integrated circuit;
a metallic foil layer having a peripheral edge that is substantially coextensive with said continuous peripheral edge of said plastic inlay, said metallic foil layer substantially overlying at least one of said substantially planar surfaces such that said metallic foil layer provides said financial transaction card with a decorative metallic reflective appearance across one or both of a front or rear face of said card;
printed graphics or text on or above said metallic foil layer; and
said card being constructed to inductively couple with an RF proximity card reader that is spaced from said card in order to support limited-range wireless communication between the card and the card reader up to a maximum coupling distance, beyond which said card will not couple.

Abstract
A contactless financial transaction card includes a plastic inlay having first and second substantially planar surfaces bounded by a continuous peripheral edge. An integrated circuit carried by the inlay stores card-specific data. An antenna carried by the inlay is operatively connected to the integrated circuit. The foil layer provides the financial transaction card with a decorative metallic reflective appearance and is constructed to permit the antenna to inductively couple with the card reader within the maximum coupling distance. Printed graphics or text may be disposed on or above the metallic foil layer. The card is constructed to inductively couple with a card reader that is spaced from the card in order to support limited-range wireless communication between the card and the card reader up to a maximum coupling distance, beyond which it will not couple.
