My view on the topic has shifted from "how can we stop this?" to instead "how can we make sure it gets implemented in a way that has the proper checks/balances to ensure citizens still have some right to privacy even when in the public?".
Personally, I am actually more concerned about the fact that every big store out there is using technology to track me as soon as I enter the store and likely has a big profile of data on me. I'm more uncomfortable with that reality and it's something that continues to happen with no restriction. Which is why I think I'd be okay with this technology as long as it has proper auditing and is kept fairly specific in when it can be used and who has access.
