Abstract
An identification card of the kind including at least two and usually three resin sheets bonded together, with identification data at an interface between sheets visible through the outermost sheet, which is transparent, and incorporates added anti-tampering protection in the form of a band or other limited area weldment between the sheets usually formed by an ultrasonic weldment; the weldment is clearly visible due to surface distortion caused by it but is not so extensive as to prevent effective viewing of the identification data in its limited area. In a more particularized aspect of the invention, a portion of the identification data is more significant than the remainder of the data and thus more susceptible to being tampered with and the weldments are placed in this susceptible area of the identification data.
