From July this year, the digital driver’s license will be used for reissuing and renewing licenses, so in time it will become the norm. In the meantime, however, users can opt in by registering their details on the app, which will form a digital license showing the user’s photo, a QR code and a bar code.

Users will only be able to use one smartphone when registering for the service, and blockchain tech will help protect sensitive data.
