| DDA: further security with third-generation bank cards |
|
| By making each transaction unique, a DDA
card constitutes a major step forward in security. |
|
|
|
With the launch of Dynamic
Data Authentication (DDA),
the current year should see
a major rollout of third-generation
bank cards in Europe.
The technological advance of dynamic
data authentication is a decisive step
forward that will make transactions
considerably safer.
• A unique signature for each transaction
After two generations of bank cards
with static authentication, the new
DDA card will contain a private key
and a cryptoprocessor enabling
it to generate a unique signature
for each transaction. This unique
signature is based on random data
that differs each time the card is used.
The authentication data is provided by the
card itself to the Eftpos terminal. After an initial pilot phase in
2004, the CB DDA
cards were introduced
in 2005. By late
March 2006, 270,000
cards had been
issued. This is only
the beginning of the
rollout of this new
technology.
• 85% of cb terminals accept dda cards

the number of EMV/DDA
CB cards in circulation. |

To date, 85% of bank card terminals have
migrated to the international EMV (Europay
MasterCard Visa) standard and so are
ready to accept DDA cards. Performance
tests in early 2006 on various CB acceptance
systems have shown that the time required for the DDA system is imperceptible
to the cardholder at the point of
sale.
In addition to its basic functions, the DDA
card has a cryptoprocessor that can offer
new services to both cardholders and
merchants, for example, e-signatures. |

"France hopes to reach
25 million EMV/DDA cards
by July 2007"
“2006 will mark the real start to the
rollout of Dynamic Data
Authentication cards in Europe.
France, Austria, Germany and
Sweden, along with other countries,
such as Indonesia and even Japan
are already issuing DDA cards.
France has set itself the ambitious
goal of 25 million EMV/DDA CB
cards by July 2007, that is half
the CB bankcards currently in circulation
(51.5 million at the end of 2005).” |
