The MT-10X/MT-26X Multi Technology Proximity Card allows the user to combine several identi cation technologies in a single credit card thin credential. The cards can be ordered with or without a high coercivity magnetic stripe, which is useful if there are other types of systems in use that are mag stripe based, such as cafeteria vending. They are also convenient for customers who may have a proximity-based access control system at one site and a mag stripe-based system at other locations, allowing the user to carry a single card. One of the most popular features of the Multi Technology Cards is that they can accept a direct print video image, typically a photograph, a bar code, and other graphics from most industry standard dye sublimation printers, to create a custom access credential. Unless the user requires the combination of mag stripe and proximity, the KC-10X/KC-26X Standard Light Card is recommended over the MT-10X/MT-26X Multi Technology Card whenever possible because of its lower cost and lifetime warranty. The Standard Light Cards can be tted with PVC label or "skinî which can accept a direct printed image to provide photo ID at a much lower cost and greater durability. Keri Proximity Credentials (including Cards, Tags, and Patches) can be used interchangeably on the same system without worry about ID code duplication or format matching.
