Abstract
A flexible card may include a dynamic magnetic stripe communications device having multiple layers, such as an electromagnetic generator, a magnet, and a shield. A shield may form a non-flexible layer within the stack and may bend, but the shield may not be able to stretch or compress. Flexible layers may surround and adhere to the shield such that when the card is flexed, the flexible layers may stretch and compress with the movement of the shield. The dynamic magnetic stripe communications device may include one or more coils. Each coil may contain a stepped material, such that a length of a lower layer of the stepped material is longer than a length of a middle layer of the stepped material which is longer than a length of a top layer of the stepped material.
