What could possibly go wrong?

Imagine Bluetooth-based advertising in the real world. Imagine you can start to identify a shopper, for example, who buys something at a store and their phone is the strongest device, perhaps paying with *-Pay. Their purchases get aggregated and advertising screens and other tech will light up for them as they pass. They buy something at a store and the assistant tries to upsell with something they bought before or might like.

While we have a little of this with store reward cards, it becomes fast, contactless and probably more effective.

That, to me, would be a reason to hope Amazon "wins" so there is no need to leave the house to get stuff
> So come on, fatso, and just bust a move. (if you're never leaving the house to get stuff)

seriously, though, what does it mean to "hope Amazon 'wins'" ? I am pulling a blank here, blanker than the blankest of blanks I've ever imagined possible.

If you're out and about, shopping and/or doing whatever else:
  • If you Bluetooth is enabled when it's not in use, the joke's on you.
  • If you use something all the time which requires Bluetooth to be enabled, is there something else you could use which accomplishes the same thing without requiring Bluetooth? If so, I guess the joke's on you too until you're using that other thing which performs the same task without Bluetooth.

Reading all this I am going to try an experiment. I use an Apple watch which uses Bluetooth as it's first choice to keep in touch with my phone. I am going to disable it for a couple days and see what effect it has on battery run time. It will still have wifi and cellular to keep in touch with the phone, but from what they say Bluetooth uses the least power. I'll post an update in a few days in case any other Apple watch users are out there.
