https://keyw.com/fred-meyer-oregon-is-scanning-your-drivers-... That's an article from September talking about how Kroger (Fred Meyer, QFC) stores in Oreogn are scanning drivers licenses for alcohol purchases and asks if Washington is next.

Locally, a large (100+) chain (Plaid Pantry) of convenience stores also is scanning licenses. Saw somebody with an Olde English 40 and a passport.

It's not the law in Oregon (or Washington) but the article says it is in Tennessee. Also says you can ask them to type in the digits of your birthdate.
