Abstract
A telephone calling card includes a planar card member with a scratch-off label positioned on a surface of the planar card member. The scratch-off label includes a base label having an opaque, releasable film layer and a PIN printed on the opaque, releasable film layer. A scratch-off cover label is secured on the base label and has a scratch-off layer that covers the PIN to obscure from viewing the PIN. Upon application of a peeling force to remove the scratch-off cover label, the opaque, releasable film layer is removed and hides the printed PIN from viewing via the backside of the opaque, releasable film layer. In one aspect of the present invention, the scratch-off cover label is folded over the base label.
