The use of single, multi-function smart cards is growing in popularity at an incredible rate. While these multi-use smart cards are extremely handy, they bring with them their own brand of security risks. This is why now, more than ever, we rely on the visual authenticity verification that comes from the use of overt security features. As the use multi-function single cards increases, so will our need for creative and effective overt security features. Today's overt security features consist of far more than photographs. Other overt security features for visual verification could include the use of optic variable ink, guilloche imaging, various holographic imaging techniques, micro-text, morphing, fine-line printing, and many more. Combined in unique ways, use of these overt security features is critical in designing an ID security card that truly foils tampering and counterfeiting efforts. We would be delighted to give you more information about these or any other security features that may be of interest to you.
