How would you even pull off a two tier system in the US. In Japan, they probably visually determine if you’re a foreigner based on race or language. That’s would be impossible in the US.
“Show state ID, driver’s license, passport, or voter registration for discount.” Could also ask to scan the state ID/driver's license 2D barcode as part of your discount program [1], which all 50 states have.
So basically I would now need to show my ID for every purchase? Not trying to make it sound like some massive obstacle, but it is just one extra annoyance I can totally live without.
And that’s without even getting into the weeds around the fact that there is a non-insignificant number of US citizens born and raised here without an ID (hence the endless controversies around proposals to implement a mandatory voter ID requirement for voting, which pop up every election cycle).
