Proton World announced that its Proton Prisma technology has successfully gone
through a series of technical tests that were designed to ensure international
interoperability of CEPS-based e-purse transactions.
The completion of these tests demonstrates that CEPS are robust, reliable and
ready for implementation by issuers and acquirers on an international basis.
The Proton Prisma technology is also used by Proton World in the Ducato pilot
CEPS were published in 1999 by a group of leading smart card industry players
to provide a global standard for e-purse interoperability. Following
publication, a number of tasks, such as the establishment of type approval
procedures and the upgrading of international networks, network simulators,
terminal and host specifications and issuing systems needed to be completed to
enable the implementation of CEPS-based systems. Card and terminal
manufacturers also needed to develop CEPS-based components that are
retro-compatible with existing e-purse technologies, to facilitate
In Ducato, Proton World’s Proton Prisma CEPS technology is used by Banksys and
Interpay. Both organisations also used C-ZAM/Smash terminals from Banksys for
CEPS load and payment transactions. The tests included the processing of
international Visa Cash transactions through VisaNet and Clip transactions
Proton Prisma can be implemented on mono-application or multiple-application
cards (combining EMV credit/debit, e-purse, PKI-based identification,
contactless transport ticketing etc.)
Visitors to Cartes 2001 will be able to see demonstrations of CEPS-based load
and purchase transactions performed at the stands of Banksys (A28), Europay
International (D44), Proton World (P44) and Visa International (F30).
Cartes 2001 thus marks the “coming-of-age” of CEPS: they are no longer mere
paper specifications: the demonstrations show that CEPS are robust and can be
successfully implemented on an international basis.
