Scan a QR code
Camera or image file. The picture is decoded on this device and never leaves it; the address is then checked like any pasted one.
FAQ
Is the camera picture uploaded?
No. Frames are decoded in the browser and discarded. This page is not allowed to make network connections.
Can a QR code contain a different address than shown next to it?
Yes — a QR code is just text. Compare the decoded address with the one printed or shown by the recipient.
