HID's Proximity and FlexSmart MIFARE contactless card combines smart card technology with the benefits of HID’s proven proximity technology. The card can be used for diverse applications such as access control, cashless vending, public transportation, event ticketing, customer loyalty and photo ID cards. Securely separated sectors enable multiple applications and support future growth. Different keys can protect read/write operations to build key hierarchies in the system. As a transition solution, the card is ideal for companies that want to add MIFARE smart card applications to an existing HID proximity technology access control system. Manufactured to the highest quality standards, HID Proximity and MIFARE credentials have the memory structure and capacity to store multiple applications on a single credential. The data is protected with encryption keys used in the mutual authentication process. Therefore, no important data will be shared until the card and reader have been authenticated to each other. When security and performance count most, HID's FlexSmart MIFARE cards can be produced with visual security and anti-counterfeiting features such as holograms, ultraviolet fluorescent inks, micro-printing or a custom logo to quickly and easily identify genuine cards.
