Intro
You're talking in person to a stranger and one of you want to send a picture or message to the other without identifying themselves or sharing contact info.
Load obsqr.io on your phone. You’ll see a QR code token, unique to this page load.
Now you have two choices: receive or share.
Explaining Receive
1.
Show the QR code on your phone’s screen to the stranger, have them read it with their phone. The token is valid for 10 minutes.
2.
The stranger’s phone will load a unique page on obsqr.io, tied to the QR code read from your phone.
3.
They can upload a picture and type/paste a message or link. As soon as they submit, the data is sent to obsqr.io, tied to the token you generated.
4.
No need to refresh. Your phone keeps checking to see if there’s a message. If so, it will show you the image and/or text the stranger sent you.
5.
For the next 10 minutes, you can download the image or text directly from your phone’s browser, unless the stranger retracted the message before you could download it.
6.
You can’t reply to the message. If they try to send another message to that same token, it won’t work.
7.
After 10 minutes, the token and the related message (if any) is inaccessible.
Explaining Share:
This is for sharing some of your content with several people in person without exchanging contact info.
1.
Load obsqr.io on your phone. Tap the “Share” 
button.
2.
Enter/paste text or link (up to 200 chars) and/or upload a picture, then hit Send.
3.
You’ll see a QR code. Show this code another phone's camera, up to six.
4.
Once the other phone reads the code, it opens a unique page where they can download the content you just uploaded. Time limit is 10 minutes. Maximum number of shares is 6. You phone will show you how many people connected and downloaded your message.
5.
You can delete your message anytime and further downloads will be prevented. This happens anyway after 10 minutes. Be aware that you don’t have control over content already downloaded.
6.
Your recipient(s) never saw any identifier or contact info of yours, you never saw any identifier or contact info of theirs. They can’t respond to your message, you can’t append yours.
7.
If you want to share something else, repeat the process.
