smart cards were critical achievements in the past 24 months, as is the synergy 
that has developed between Schlumberger and its associates to bring smart card 
applications into people's lives for ID, stored value, banking, network 
security and access control, self-service kiosks, frequent buyer programs, e-
commerce, healthcare data management and more.
