Upgrade any proximity system to take advantage of encrypted communication protocols without replacing expensive control panels or software. SMA (secure, mutually authenticating) Proximity cards use proprietary encryption to keep access control data secure and prevent sniffing or cloning. SMA Proximity cards and readers do not use factory set cryptographic keys. Instead, every system requires the owner to setup a proprietary secret key. This means that once an SMA Proximity system is deployed – it is extremely secure.

This medium-security access control smart card is designed to work with the MIFARE open standard using ISO 14443-3 type A communications and available in 1K or 4K formats. MIFARE cards are memory storage devices, where the memory is divided into segments and blocks with simple security mechanisms for access control. They are widely used for electronic wallet, access control, corporate ID cards, transportation or event ticketing. 1K MIFARE cards offer 1024 bytes of data storage, split into sixteen sectors. 4K MIFARE cards offer 4096 bytes split into forty sectors. of which 32 are same size as in the 1K with eight more that are quadruple size sectors. MIFARE uses an NXP proprietary security protocol (Crypto-1) for authentication and ciphering.

High security RFID memory cards with support for Triple-DES, 128-bit AES encryption, random ID and virtual card architecture. Available with 2 KB, 4 KB or 8 KB memory, DESFire EV1 cards are backwards compatible with legacy MIFARE® systems.

Securicards contact chip smart cards are the same size as a standard CR80 card but also have a single embedded chip. The card is inserted into a reader and information is read or written on to the chip via electrical connectivity with its gold-plated contact pads. The embedded integrated circuit chip can either comprise just memory, or it may also contain a microprocessor. Memory-only chips are more cost-effective but offer less security and less flexibility. Information on chips with a microprocessor can be updated securely and can also contain enhanced security features (such as for EMV payment cards) to protect the contents of the chip’s memory from any unauthorised access.

Multiple card technologies can be combined on one single Securicards card. This enables the seamless migration of an access control system from, for example, magnetic stripe communications to high security SMA proximity. Multi-technology cards are also a flexible solution for an access control system containing more than one type of communication interface or for interoperability between sites and systems.
