Contactless smart cards offer a convenient, secure way for building access. Compared to traditional technologies such as mechanical keys or mag stripe cards, they offer more flexibility and ease of use for Smart City designs.
Many systems are based on popular NXP® ICs such as MIFARE™ Classic or Hitag. For systems requiring high security, we recommend to use MIFARE® Plus™ or MIFARE DESFire™ EV1. These ICs are common criteria certified and base their security architecture on proven open cryptography. MIFARE DESFire® also provides a flexible memory based on a 7816 file system and the choice of 3DES or AES cryptography.
In addition to the physical access to buildings, a secure smart card can also protect the logical access to PCs.
Using a feature exclusive to NXP®, called low-power card detection, the reader terminal’s microcontroller enters sleep mode while still polling for cards, thus ensuring energy-efficient operation.
NXP uses the most robust, mass-tested NFC technology, minimizing interference from magnetic fields, which can come from metal in the door or doorway.
