Navy uses smart cards to speed travel process

The Navy is the first department in the Defense Department to use Common Access smart cards for the Defense Travel System.

'I put my claim in, and it's all done electronically in a few days,' said David Wennergren, deputy Navy CIO and chairman of DOD's Smart Card Senior Coordinating Group.

The travel system, nearly a year old, connects to 40 accounting and disbursing systems, the Defense table of official distances, per-diem rates, a repository for records management and DOD's public-key infrastructure. The smart card has an embedded private key that works with the PKI component, 'so I can digitally sign a travel order request,' Wennergren said. 'But you need security, particularly digital signatures.'

Although Defense Travel System users have been making online travel reservations since the fall, verification and approval until now have been mostly on paper, Wennergren said.
