ABSTRACT:
A credit card or security card data processing system employing portable ds including data processing means in each card adapted to be coupled to a data processing station having its own data processing means. In each card a part of the data processing means is formed by magnetic bubble elements at least one of which is a memory. The magnetic bubble elements are formed in a layer of magnetic material which has a propagation track thereon and which is positioned between a pair of magnet elements which establish a polarizing field perpendicular to the layer. The operating station includes orthogonal conductive coils arranged to set up a rotatable magnetic field which is applied to the magnetic layer causing the bubbles to be attracted by magnetic poles in the propagation track. A magnetoresistive member senses movement of the bubbles.
