Bologna, Italy -Announced at January's Union Internationale des Transport Public conference, an international transit industry conference on automated fare collection, Motorola's M-Smart Mercury™MM4000L smart card claimed several industry "firsts." Motorola ASIC technology, optimized for contactless smart cards, allows features normally found only in higher-priced microprocessor cards. As a result, says Mario DiPrizio, director of engineering and product development for the Motorola Worldwide Smartcard Solutions Div., the card provides cost-effective contactless transactions for high-volume applications such as mass transit.
Card components that help include the built-in data encryption standard (DES) engine, block addressing, and high-speed communications. Other features: 1 Kbyte of secure EEPROM read/write memory; a 10-cm read range; and three security options-triple DES, single DES, or pass through.
The systems architecture that lies behind the card includes reader devices and back-office systems. Multi-application and security features create the possibility for new card uses such as the secure reloading of transit fares over the Internet.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
