Nissan Europe is rolling out a smart card system to give employees in 34 countries access to IT systems and buildings.
The project was started in 2005 and so far employees in 29 countries, including the UK, have been issued with Nissan ID cards.
The business benefits of the system included reduced support and management costs and tighten security across the organisation, said Graham Orton, Nissan Europe's office technology and security manager.

The Nissan ID card allows employees to access and exchange confidential information across the network as well as access systems shared with alliance partner Renault.
The Nissan combined ID builds on a smart card building access system introduced by Nissan Japan in 2001. Nissan has used cards and readers bundled with management, authentication, remote access and security software from ActivIdentity.
Orton said Nissan chose the smart employee ID product from ActivIdentity because it was the only field-tested system that was able to scale to 100,000 users and allow credentials to be added as the company's needs changed.
The choice of ActivIdentity also enabled smooth integration with Nissan Japan's access system which uses the same same software, he said.
