No more paper counterpart driving licences - what does it mean?

Like bomb, I will be hiring a car for a holiday in the US later this year so I was interested to see how the new system works. I actually logged on successfully to the .gov.uk website this afternoon and viewed both my licence and my partner's. (If you Google "view my licence" you'll find the site easily.) You are given two choices, either to "view", in which case you see full details of your licence, or "share", in which case you are given a code to pass on. All the details of both our licences were present and correct. Rather than bother obtaining the "share" code(s) which expire after 72 hours, I wonder if, at the hire car desk, you could simply log on as I did today on your tablet or smartphone, "view" your licence details and hand the device to the hire car agent so they can verify it? Hopefully, there could be an even simpler solution in time. I hired a car from Alamo in Los Angeles last September and, if I recall correctly, their system asked me to provide my licence number before I travelled. It wouldn't be difficult for them to enhance this to ask for a "share" code as well, so all the relevant checks could be made before you arrive at the desk. All of this, of course, depends on the system being robust and totally reliable so, like bomb, I won't be destroying our paper counterpart licences anytime soon!
