Plastic cards with included electronic elements are made by laminating a carrier sheet bearing multiple electronic elements between top and bottom plastic sheets. The laminated composite is die cut into separate cards. Prior to lamination the carrier sheet is perforated in a web pattern such that the carrier sheet material is largely recessed from the side edges of the finished cards for better lamination and appearance of the finished card edges. The electronic elements may be obtained on continuous rolls of carrier material which is cut into sheets for lamination.
