Yes, this idea would be interesting if acceptance were mandated, but I'm not aware of any movement in that direction in any state. Mandating this kind of system would be massively fraught with political and legal peril in the US and is likely impossible. With the way the US works, there needs to be an incentive for businesses to use these systems, and I haven't seen an implementation with this focus yet. Bars would p…
I’m thoroughly confused by your first paragraph. It seems like it would be basically trivial to mandate acceptance of a digital ID system, at least within one of our 50 laboratories of democracy. Step 1: State adopts digital ID system and mandates that subdivisions and political units of the state are required to accept it for identification purposes in their interactions with the public. Step 2: Step 1 is extended t…
This the part which I believe would be extremely difficult to do by mandate given the current US social and political climate, which is why I think there needs to be some form of market incentive for these private actors.
> I also don’t think there necessarily needs to be an incentive for businesses to invest in expensive card reader systems that phone home to a database and authenticate the QR displayed on the device.
Thankfully nothing needs to phone home anyway, and there is no accessible database. It's all PKI based - the device attests certain facts and the reader verifies these attestations. A reasonably effective system which (for example) corner liquor store owners are going to want needs to exist to perform validation, though.
> Instead, just change the law against selling liquor to kids saying that a good faith effort to validate the authenticity of state issued digital ID is a defense to prosecution under that law. In my state, at least, this is basically how it works now with physical ID cards.
This would be the kind of incentive that I think would help a lot - if! a "good faith" effort to verify a digital ID were easier than a physical one. If using the digital system helps protect liquor vendors from liability and/or police sting operations, that's a huge incentive to use the system.
