About the email qr code
The code contains a mailto link. Scanning it opens the phone's mail app with a new message addressed to you, which is a good deal more likely to result in an email than printing an address someone has to type.
Spaces in the subject and body are percent-encoded rather than written as plus signs. Some tools use plus signs, which several mail clients then display literally in the subject line.
Frequently asked questions
- Is anything I enter sent to a server?
- No. The QR code is generated by JavaScript running on your own device, and nothing you type - a Wi-Fi password, a phone number, a contact card - is uploaded, stored or logged. You can disconnect from the network after the page loads and it keeps working.
- Does it send the email automatically?
- No, and it could not. It opens a draft in the reader's own mail app; they still choose to send it, and can edit anything first.
- What if they have no mail app set up?
- Nothing happens, or the phone offers to set one up. That is worth bearing in mind for a public poster - a plain link or a phone number may reach more people.
- Do these codes expire, or need an account?
- No. The code contains the content itself rather than a link to us, so there is nothing to expire, nothing to track and no service that can stop working. Once you have downloaded it, it will keep scanning forever.
