Abstract

A card construction is adapted for preparation of several information-carrying mediums, insertion of the mediums and completion of the construction at a location different than the location for the prior manufacturing of the construction. The construction is particularly formed to avoid false indications of a card edge in apparatus which receives the card, e.g., to read magnetically-coded information on the card or to initially encode such information on the card. The card construction incorporates: first and second protective coverings, each capable of transmitting information through the covering; and structure between the coverings defining first and second openings, the first opening disposed toward the first protective covering and the second opening disposed toward the second protective covering; wherein the openings have boundaries, along a boundary of the card construction, which are out of registration with one another. One of the protective coverings carries magnetic material for magnetically-coded information. In addition, the openings each have substantially rectangular-shaped boundaries and this boundary of one of the openings is disposed inwardly of the boundary of the other opening. The structure defining the openings incorporates substantially opaque material.
