Sometimes it feels ridiculous how much OPSEC I need to employ to buy anything at the grocery store. I walk or bike to the store to not reveal a license plate. All radios and sensors on my handset are turned off. I wear a mask to thwart facial recognition cameras. I pay cash.

> I pay cash. Can we, today, be sure that ATMs do not record serial numbers of the bank notes they dispense?

I wouldn't mind so much if they also gave it to me. But my grocery points card sells my shopping list to everyone else BUT me. I've looked, and PC Optimum doesn't provide line items back to the consumer.

So rude. Just like Experian and friends. Keeping detailed notes on me, and acting all surprised when I want to read them. It's like they are embarrassed I actually exist.

> his is fine, but it's not really about tracking you, it's about tracking the habits of shoppers in aggregate, of which you are a participant. (Yes, having your real address to mail flyers is a bonus but not the end goal.) Like hell it is. This is an article about Target back in 2012, that identified a pregnant underage girl purely from her purchasing record. 11 years ago. https://www.forbes.com/sites/kashmirhill/20…

That is not necessary any more now.

Now, when there are riots, it is well known that police has human "super-recognizers", which can scan thousands of photos and identify suspect individuals on a whim.

IME at Safeway if you don't use a "club card" you end up paying nearly double for many items. Are there ways around this?

Be me, 35 and using my parent's phone number for their club card.

If the loyalty account is based on a phone number, try entering your local area code plus 867-5309. I've found this works at every major supermarket and gas station. Sometimes you get slight discounts because other people also enter this number and the account accrues points. The other option is to sign up using a fake persona and a burner email. Typically rewards programs don't audit information or ever ask you to u…

Unless you only pay with cash, that fake profile gets tied to your real credit card, so I'm not seeing what that gets you.

At my local store, the checkout clerks keep pushing me to get a loyalty card. I tried to engage once and start a conversation about privacy, but ended up walking away from the conversation feeling a little like a conspiracy theorist. But thanks to working in tech, I know this data is being tracked, bought, and sold behind the cute "loyalty" branding. I wish I knew of a good way to convince ordinary people to value th…

My local food store still give me sticky small olive labels which can be collected in a booklet, which earns an discount once it is full. I love that. And they ask me every time if I want my olives.

If they don't, that's the best startup idea I've heard on HN in a long time. I mean, it's evil and everything, but you could make a lot of money probably. Government contracts would probably pay out too.

Edward Snowden revealed that u need to remove the battery on ur phone to make it "safe", turning it off doesn't do the trick. [Which u can't do anymore]. As another commenter says: leave the phone at home.

What about a Faraday bag?

theoretically the phone could still record all audio and then sync with the cloud when back online, but I'm grasping at straws here.

Local area code + 867-5309

In my formative years I rode the CTA a lot, and they always had an announcement, "call 836-7000 for transit information". The number was burned in my head and it's worked in every store I've tried. (You can add any Chicago-area area code; 847, 312, etc.)

Yes, it worked at a Safeway in San Jose too. I love that someone also had this stuck in their head and used it to sign up for grocery discounts.
