To the proposals being put forward for connecting smart cards to  computers, a French entrepreneur wants to add the lowly mouse. 
To stress how his invention is different, Cornel Sirbu calls it Personal  CAT-Conditional Access Terminal. 
  
Mr. Sirbu and his company, Silcor of Guyancourt, France, unveiled  Personal CAT in June at Interfinances '98, a trade show in Paris. 
It has the look and feel of a personal computer mouse but is noticeably  thicker and heavier to accommodate a chip card reader. Flipping it over   reveals a 12-key numerical pad and two-line liquid crystal display for   entry of personal identification numbers and other data.     
  
"This has total interoperability," Mr. Sirbu said. "It connects to any  computer port," theoretically enabling card activation and many forms of   electronic commerce or loading of cash value.   
Computer manufacturers are moving toward smart card readers in  keyboards. Vendors such as Gemplus and Verifone offer streamlined card   entry devices. Microsoft has announced an initiative to support the   standards of the PC/SC Workgroup, with which Mr. Sirbu said Personal CAT   will comply.       
All tend to agree it will be years before PC card readers are common,  and Mr. Sirbu sees CAT as a logical transition. 
  
He said he began thinking this out two years ago. "The device had to be  close to the user, handy, user-friendly, and simple to connect," he said. 
He described the result as "an upside-down smart card terminal, its back  having the look and ergonomics of the common mouse. ... It is the only   smart card terminal that replaces the mouse and takes over the pointing   function as well."     
Mr. Sirbu sees the bulkiness of Personal CAT as a potential advantage.  Bankers and their customers would regard it as "not cheap." 
Mr. Sirbu is working with a consultant in New York, Andrei Racz, who he  hopes can help CAT get noticed by those conducting the Mondex and Visa Cash   market trial.
