Abstract
Convenient, portable chargers for recharging a secondary battery in an electronically readable card which can be in sleeve form. The portable chargers are lightweight and portable and desirably have dimensions that are not much larger than those of an electronically readable card. The chargers may include a connector such as a sleeve for securing an electronically readable card, a power source for providing recharging power and a power interface for delivering the recharging power from the power source to the electronically readable card. The power source may take on a variety of forms including another battery, a photovoltaic array or a direct plug connection to a electric wall outlet, Universal Serial Bus port or a telephone jack. In some embodiments the portable chargers charge the battery in an electronically readable card by inductive coupling.
