Abstract
A powered card may include a plurality of types of sensors used to detect a read-head of a card reader. Detection of a read-head may include comparing characteristics of a detection event to characteristics of an expected detection event and/or a sequence of expected detection events. An inductive read-head sensor may include a coil of a dynamic magnetic stripe communication device.
