It was announced as part of the 2019-20 NSW Budget that drivers will able to opt-in to use a NSW Digital Driver Licence (DDL) in the coming months, as the technology is rolled out state-wide.

More than 14,000 drivers are already using the technology, available via the Service NSW app, with successful trials underway in Dubbo, Albury and Sydney's Eastern Suburbs.

Participants who opt-in can use their DDL, accessible on a mobile phone, for proof of identity and proof of age to gain entry into pubs and clubs as well for roadside Police checks in the trial areas.

"Innovation is at the heart of this Budget and nothing shows this more than the rollout of the Digital Driver Licence," Treasurer Dominic Perrottet said.

Minister for Customer Service Victor Dominello said the Government is delivering on a promise, with the trials helping to inform the state-wide rollout of the technology.

"The DDL is hosted securely on the new Service NSW app, locks with a PIN and can be accessed offline," he said.

"It will provide additional levels of security and protection against identity fraud, compared to the plastic driver licence."

To participate, eligible licence holders should create a MyServiceNSW Account at www.service.nsw.gov.au , download the Service NSW mobile app on their smartphone and opt-in for the DDL.

During the trials, drivers who opt-in will still need to carry their plastic driver licence with them.

The DDL will always be opt-in only.
