To prove that the car rental company has seen the driver licence, they just need to show the judge a copy of the licence which is e-sealed by its issuing authority. No need to include a non-repudiable proof-of-possession signature of the holder. Having that in addition would just introduce legal ambiguity and information asymmetry to the disadvantage of the holder.
The opponent may still claim that the car rental place is showing a copy that was obtained illegally, and not in holder presentation. To avoid such a claim, the car rental company should ask for a qualified e-signature before providing the car key. The signed data can include any relevant claims that both parties confirm as part of the transaction. To provide similar assurance to the customer, the company should counter-sign that document, or provide it pre-sealed if it is an automated process.
Note that with the EU Digital Identity, creating qualified e-signatures is just as easy as presenting digital credentials.
Getting the parties on the desk, or the people commissioning enterprise IT systems, to understand this is going to be a serious uphill struggle. Especially in places that are used to photocopying your ID.
the liquor store owner that scans the barcode on your Driver's License "does not understand" and does not care to understand. Yet the opening to your entire life to some low-level cog has been transferred. The correct answer for the wonks out there is : scan ID to answer the question "is this person over the legal drinking age" YES or NO .. which is stored. Similar situations with different contexts, abound.
