Fair Isaac Partners with Aconite to Deliver More Powerful Fraud-Fighting Capabilities

Fair Isaac Corporation (NYSE:FIC), the leading provider of
analytics and decision management technology, and Aconite, a leading
provider of software and consulting solutions to the global payments
market, today announced they have joined forces to provide banks and
transaction processors worldwide with new capabilities to better
manage fraud and risk in an off-line EMV environment.

The announcement was made at Fair Isaac's InterACT customer
conference in Lisbon, where Aconite is co-presenting a session on the
evolution of fraud and risk management.

The companies will jointly market Fair Isaac's industry-leading
solutions Falcon(TM) Fraud Manager for payment card fraud detection
and TRIAD(TM) adaptive control system for credit risk management with
EMV Script Processor (ESP) and EMV Transaction Enabler (TRxE),
Aconite's award-winning EMV software solutions. Together, these
solutions create powerful new capabilities designed to help banks
adopt a balanced online/offline authorization policy, reduce
operational costs, minimize fraud losses, and increase revenue through
secure approval of more transactions and improved customer
satisfaction.

"This partnership reflects the strong demand for integrated EMV
solutions that provide full fraud and risk management capabilities,"
said Mike Woods, CEO of Aconite. "Together, we can offer our clients
the industry's most advanced solutions to fine-tune offline and online
authorization and maximize the benefits from offline authorization,
while minimizing credit risk."

Aconite's EMV solutions were designed to integrate easily with
existing host systems, allowing the generation, management and
delivery of scripts to change card parameters dynamically after issue
and securely manage offline risk. The Fair Isaac and Aconite solutions
can be easily combined with clients' existing systems as individual
advanced fraud and risk management solutions or as part of a broader
EMV migration package.

Named after its originators Europay, MasterCard and Visa, EMV
describes a set of requirements to ensure interoperability between
"smart" or chip-based payment cards and point-of-sale terminals on a
global basis. Through the partnership, card issuers will now be able
to harness the power of EMV, using Falcon and TRIAD decision
management and TRxE and ESP functionality to securely push more
transactions offline by dynamically updating and controlling card
behavior after issue.

"Joining forces with Aconite underscores our commitment to
continual innovation and bringing best-in-class technologies together
with our leading solutions for fraud and risk management," said Andrew
Jennings, vice president, Enterprise Decision Management Applications
at Fair Isaac. "Forward-thinking banks are already unlocking the
potential of EMV to grow revenues while controlling fraud losses and
the cost of managing the portfolio. Banks that utilize TRxE and ESP
with TRIAD and Falcon will multiply that potential and be on the fast
track to EMV migration."

The companies also plan to develop consulting services to help
customers migrate to EMV and achieve their risk management goals for
credit and debit card portfolios.

Fair Isaac's Falcon Fraud Manager is considered the leading global
payment card fraud detection system, protecting more than 450 million
active accounts across six continents and saving card issuers millions
of dollars every day. Falcon applies neural network technology,
extensive rule development capabilities and workflow management to
analyze payment card transactions for signs of fraud, and enables
financial institutions to take immediate measures to stop fraud and
reduce losses. TRIAD adaptive control system automates and improves
account and customer management decisions to drive portfolio
management performance and is used to manage nearly 300 card
portfolios across industries worldwide.
