I can't speak for this shop's usage in particular, but this remains a "paper, please" from me, until I'm confident a shop will:- only use my email address to send the receipt. No marketing. No "service messages".- doesn't use it for profiling / tracking without my consent.

@neil I can't believe there's much environmental benefit either, being paper and small.

@penguin42 @neil The shop doesn’t likely care about the eco angle. Most likely the shop likes the fact that there will be fewer receipts in the trashcan just outside the door, which thieves harvest before walking into the shop. They find an item in the shop that appears on the receipt, then return it for cash.

The DuckDuckGo app on your phone can quickly generate a disposable email address. Just give them a unique email address for every transaction. :-)

@gme I do that already, but I don't think people should have to resort to technical workarounds

Fair enough. Personally, I don't see it as a workaround.A retailer asks for my number I give them 867-5309. If they won't accept that then I give them 202-456-1111 (The White House).A retailer wants my email address? I give them donotemail@[my domain]. Which is a valid email. But any email received is bounced back with a demand to stop emailing. If they won't accept that then I give them thisisavalidemailaddress@[my domain]. Which pretty much does the same thing. I don't block the senders' domain because I might want to get some email from them.But between those two tactics it usually works.It's not worth the time and effort to fight the cashier or check out person asking for this stuff. They're just doing their job and following company policy.The reality is they don't need our email address or phone number to track us anyway.99% of retailers have bluetooth scanners that record the MAC address of every bluetooth device (phone, air tag, etc.) that comes in the store, and there are readers at every cashier station. They know who you are and whether you've visited before the moment you step foot inside.

@gme (In my case, not via DDG, but just a catch-all on the mailserver, for simplicity.)

I'm using the duckduckgo app more because that way I can easily deactivate the address and never have to worry about it again. With a catch-all it's a little more cumbersome. Though I do have those too.

Though I do have those too.But mainly for online stuff. I've only used it once at a computer store that was being exceptionally obtuse with me when all I wanted to do was to pay for my goods and leave.

@neilFrom what i understand bluetooth privacy is pretty good on smartphones now (maybe not on old/cheap devices?) and doesnt provide any unique persistant identifier?And why not just turn bluetooth off when not using it?Anyway it feels wrong to just give into all the advertising/marketing bs @gme

Except if the MAC address really did constantly changed on your BT device you'd have to re-pair it every time you wanted to use it.

Yeah but that's more about protecting your devices from interception. The tracking technology that most sticks & bricks retailers are using today doesn't care about your device or about what you're transmitting (or receiving). Only thing it does is listen for the BT/BT-LE "pings" from your devices that all BT devices emit. That's it. Nothing more.From there they can infer how many people have entered their store, what they might be buying, and what they DID buy (because there are receivers at every cash register.)So they may not know that iPhone belongs to you at first but if you pay with a credit card they will then confirm that it does. And if it's not your iPhone then it's your Air Tag that you have clipped to your purse, or the BT headphones that you're wearing, or that Samsung or Apple watch that you're wearing.

@gme @neil Theres also pretty good wifi privacy on decent modern phones - which took addressing persistent identifiers other than the MAC address.Pixels and other decent phones spoof a different mac address to each wifi network, so you can be recognised (eg. for the network at a place of work) GrapheneOS changed it so the default is a different mac every time you connect.

Indeed. I've had this going back as early as Android 10 I believe, if not sooner. (I'm on Android 13 now on my Pixel 4XL). The poor WiFi router for my AT&T Fiber thinks I have 50 or 60 people in my house when it's just me (thanks to the MAC address randomization).But again, I'm talking Bluetooth, not WiFi.

@gme I dont really use bluetooth for anything.Very few people I know do either (poorer and/or less tech dazzled folks largely living out of the cities).Smart watches still arent that common. That and cars have to be the main pushes for regular use of BT. Lots of people dont ever use any type of headphones with their phone.

Maybe where you live but you can't stretch that generalization to everywhere.Certainly in cities, on public transport, and pretty much most places where smartphones are prevalent then so is Bluetooth.And I'm not so sure about smart watches either. Keep in mind even FitBit activity trackers have Bluetooth. Not to mention all the Tiles and Air Tags.It's ubiquitous.

Well, "99%" by its very statement is not absolute. That would be "100%".And Webster defines "ubiquitous" as:

@gme well almost absolute 😁(couldnt think of a better word and was being lazy) guess my point is that theres likely a whole load more folks (and shops) in the world, than you imagine, that dont fit your presumption of whats very common

For sure. But then again, mom & pops (and your local bodega) aren't trying to compete with internet e-tailers like your large shops and chain stores. Those are the one's you're most likely to find the technology.Not to mention, with profit margins being as thin as they are mom & pops probably can't afford (or justify purchasing) the technology in the first place.
