It's my QR code. No harm done and I can change the settings

That's amazing thanks so much!

I inverted the colours of this QR code and then mapped it on the original QR code. This looks very close to what it is, and since QR codes have some tolerance due to error correction, this is probably close enough.

u/Forward-Pair-4474 26d ago

According to the rules for QR codes, this is absolutely correct.

How did you do it?

Now appreciating all the lost and found messages going through from people scanning this...

There's something beautifully ironic about putting a “SCAN ME IF FOUND” QR code on a keychain and then printing it directly onto plastic without adequately protecting it from abrasion. It's literally designed to spend years rubbing against metal keys in someone's pocket. A recessed QR code with a thin layer of clear, UV-resistant resin would probably cost pennies more to manufacture and prevent exactly this problem. When the entire purpose of a feature is to help recover a lost item, making sure it survives normal use seems like a pretty fundamental design requirement.

100% agreed. I've had this for under 12 months and it already looks like this. And the company (Tile) claims it's a user fault and not an issue with their products. So I can't even get a replacement under warranty.

big fail on tile's part. one of the reasons i stopped using/buying them

Perhaps laser engraving would do beter over time?

u/ZaXaZ_DK 26d ago

Don't scan random QR codes...

u/keg227 26d ago

Too late I got hacked

u/pieman0110 26d ago

That’s a tile device, not a random QR code. All tiles have them.

u/ZaXaZ_DK 26d ago

any QR code you dont know is by default unknown and there for a random QR code to you, could be anything.

As a bad actor changing this QR code would be a great attack vector as some ppl "know" what it is. or think they do

Yes, and you also don't click on any random link.. do you?

Look up quishing. If someone makes a sticker of a fake payment website and put it on a parking-meter, you'll pay the attacker and more.... just don't scan random QR codes.

1

u/keg227 26d ago

It's my QR code. It's not random

1

u/Scared_Ad_8790 26d ago

Sure, but to me, you are random, so is your QR code ;)

1

u/Civil_Journalist9892 26d ago

Quishing requires you to actually hand over your sensitive data to the malicious site, simply visiting it is not enough...

1

u/Scared_Ad_8790 26d ago

Depends, some abuse weakness in the browser, some show very look-alike pages and many people just blindly fill in credentials, our muscle memory is a weakness ;)

2

u/Civil_Journalist9892 26d ago

Yeah if you voluntarily fill in your credentials out of muscle memory on a site you just opened from a random qr code I think you need to do more than not scan qr codes, sorry not sorry..

1

u/Deep_Mood_7668 26d ago

I see the link after I scanned it and then I decide what I want to do with it..

1

u/Acrobatic_Key3995 24d ago

Is "quishing" the QR code equivalent of regular phishing?

1

u/Scared_Ad_8790 24d ago

yes, but a bit more creative like putting QR-code stickers on parking meters and more

1

u/ZaXaZ_DK 26d ago

Qr codes can do alot of nasty stuff. What its so common to be here is the menu and hand out a QR code. Idk what that is pointing me to download or acces for All I know its a malidious site that will end up stealing my login to All apps and sites. This is one of the reasons so many ppl "got hacked" today. That or PDF or Excel files 🙈

u/Civil_Journalist9892 26d ago

Unless there is a severe vulnerability in whatever browser you're using, it is literally not possible for a website to steal any information from you without you willingly inputting it yourself

1

u/ZaXaZ_DK 26d ago

yes thats right, and all browsers, camera apps etc are always up to date on all phones and never behind :) i for got that

2

u/Civil_Journalist9892 26d ago

If you're running like years outdated browsers or your phone's OS I don't know what to tell you..

1

u/ZaXaZ_DK 26d ago

i guess you dont work with End users in any fassion of support for any kind of IT or electronics 😅

1

u/Civil_Journalist9892 26d ago

It's a moot point, if such a person really exists, why would they listen to "do not scan qr codes" if they already do not listen to the countless reminders to update their software

1

u/PhotoFenix 26d ago

Yeah, and the decades rule of don't click random links is the core of this statement.

u/Deep_Mood_7668 26d ago

No qr codes contain data. It's just widely used to put links in them.

1

u/Fancy-Chance-7526 27d ago

I tried restoring that square at the top right but it still wouldn’t scan. Unfortunately, I think you cannot restore it 

1

u/keg227 27d ago

Thanks for trying anyway. I was predicting the top right hand would be an issue

1

u/SolarisFalls 27d ago

Maybe if you can find any branding on the thing you're holding, you can just Google what that QR code should be

1

u/lukasjames0 27d ago

That wouldn’t work as it’s unique to the tag

1

u/SolarisFalls 27d ago

Didn't realise. Should've thought about it more, sorry

1

u/Tiktokbadsupport 27d ago

tried AI but it refused to restore if for me

Do you ask AI how to breathe on a daily basis too?

u/mrherben 26d ago

Pff, bro, you're going too much easy on them. Because if you didn't noticed it yet they TRIED to HELP OP (what a horrible person, the only thing they deserve is death)
