Abstract
A self-contained purse-like electronic fund transfer device mainly for use in personal payment transactions, designed to be in the permanent possession of the user and featuring electromagnetic power injection from, and data transfer coupling with, a data terminal. A reader unit has a displaceable concave portion and the handheld personal payment device a convex portion in which the active flux carrying conductors are embedded in such a manner that relatively large angular shifts between the two parts do not interfere with the efficiency of the coupling or the speed of the transaction.
