Re: It Bodes
"And does having a flat battery count as "failure to produce valid documents" ?"
Look beyond such pitfalls, and remember that for the end user there will be "increased convenience". They will achieve this by coupling the digital licence "with the increased use of biometric, multi-factor and secondary authentication techniques".
So when you show your digital licence (or fail to do so because of a flat battery) you may also need to supply a secondary form of identity, or do something else to help authenticate your identity.
