QR Handler Blog #
Plain guides to the codes you meet every day: scanning them on any phone, making your own for Wi-Fi, contacts and links, fixing codes that won’t read, and telling a genuine code from a sticker someone put there. Where safety is involved we follow the FTC and FBI guidance and say clearly what a scanner can and can’t catch. The blog comes from the team behind QR Handler, a free iOS and Android app that shows the full contents of a code before anything opens, works offline and keeps its history on your device.
