Abstract
A transaction card for communicating data relating to a transaction may include a metal layer; a backing layer; and/or a radio frequency (RF) antenna layer positioned between the metal layer and the backing layer, where the RF antenna layer includes an RF antenna that may facilitate communicating the data relating to the transaction wirelessly via an RF signal, and the metal layer includes a plurality of holes to limit eddy currents in the metal layer to a threshold density, where the plurality of holes may extend from a top surface of the metal layer to a bottom surface of the metal layer, and the eddy currents may be caused by the RF signal.
Claims21
A transaction card for communicating data relating to a transaction, the transaction card comprising:
- a metal layer;
- a backing layer;
- and
- a radio frequency (RF) antenna layer positioned between the metal layer and the backing layer,
- where
- the RF antenna layer includes an RF antenna to facilitate communicating the data relating to the transaction wirelessly via an RF signal,
- the metal layer comprises a plurality of holes,
- the plurality of holes extending from a top surface of the metal layer or a bottom surface of the metal layer to a middle plane of the metal layer that is between the top surface and the bottom surface.
A transaction card, the transaction card comprising:
- a metal layer;
- and
- a radio frequency (RF) antenna layer positioned adjacent to the metal layer,
- where
