HID Global's SIO®-Enabled MIFARE + Proximity cards are part of its next-generation SIO-enabled access control platform and open ecosystem based on HID's Trusted Identity Platform® (TIP™) architecture. Going beyond the traditional smart card model, the platform offers a secure, standards-based, technology-independent and flexible identity data structure based on Secure Identity Object™ (SIO), HID Global's new portable credential methodology.

HID MIFARE credentials have the memory structure and capacity to store multiple applications on a single credential. Securely separated sectors that are each protected by a set of two keys and programmable access conditions allow complex applications and provide for future expansion. The data on the card is protected with encryption keys used in the mutual authentication process.

Note: Some cards and/or formats may require a minimum order quantity of 100 cards.
