Abstract

A payment card (e.g., credit and/or debit card) is provided with a magnetic emulator operable to act as a magnetic stripe read-head detector and a data transmitter. A multiple layer flexible PCB may be fabricated to include multiple magnetic emulators. Layers of the flexible PCB may include magnetic shielding in order to reduce interference from the magnetic emulators to particular read-heads on a magnetic stripe reader.
