For the past several years, the vast majority of EMV banking cards banks have ordered have complied with the cheapest option within the global standard. That option, called static data authentication, while much more secure than magnetic stripe cards, are technically vulnerable to cloning. This has forced banks in many countries to send most of their transactions online for authorization. Smart card vendors have pushed a higher-security option in the standard, called dynamic data authentication for years. Now, according to figures released last month by the Smart Payment Association, a vendor trade group, banks - led by those in France-are finally beginning to move to DDA. The association says more than 27% of the EMV banking smart cards the four vendors shipped during the fourth quarter of 2006 supported DDA.
