Abstract
A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Such a magnetic emulator may comprise non-magnetostrictive material such that the magnetic emulator may be fabricated in a wide variety of fabrication processes. Additionally, magnets may be added to amplify the signal of a magnetic emulator. In doing so, a magnetic emulator may provide a large amount of signal while consuming a reduced amount of electrical energy when compared to a magnetic emulator that does not include the presence of one or more magnets.
