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.
Claims20
A transaction card for communicating data relating to a transaction, the transaction card comprising:
- a metal layer having a thickness between 12 thousandths of an inch and 18 thousandths of an inch;
- 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, and
- the metal layer comprises a plurality of holes to limit eddy currents in the metal layer to a threshold density,
- the plurality of holes extending from a top surface of the metal layer to a bottom surface of the metal layer, and
- the eddy currents to be caused by the RF signal.
A transaction card for communicating data relating to a transaction, the transaction card comprising:
- a first metal layer comprising a first plurality of holes to limit eddy currents in the first metal layer to a first threshold density,
- the first plurality of holes extending from a top surface of the first metal layer to a bottom surface of the first metal layer, and
- the first metal layer having a thickness between 12 thousandths of an inch and 18 thousandths of an inch;
- a second metal layer comprising a second plurality of holes to limit eddy currents in the second metal layer to a second threshold density,
- the second plurality of holes extending from a top surface of the second metal layer to a bottom surface of the second metal layer;
- and
- a radio frequency (RF) antenna layer positioned between the first metal layer and the second metal layer,
- where
- the RF antenna layer includes an RF antenna to facilitate communicating the data relating to the transaction wirelessly via an RF signal, and
- the eddy currents in the first metal layer or the eddy currents in the second metal layer to be caused by the RF signal.

- the plurality of holes extending from a top surface of the metal layer to a bottom surface of the metal layer,
- where a first subset of the plurality of holes that overlap the RF antenna are positioned more densely than a second subset of the plurality of holes that do not overlap the RF antenna, and
- the eddy currents to be caused by the RF signal.
