Hologram ID cards utilize holographic stickers or overlays to increase visual authenticity. Holograms appear to differ by the light and angle at which they are viewed. They are difficult to remove, alter and duplicate.
Many laminating ID card printers are capable of producing holograms. Some printers require only a field- installed module to upgrade to holographic capability. An economical way to produce hologram ID cards is to add a self-adhesive sticker or overlay by hand.
