Short answer: you usually can't tell just by looking. A QR code is just a link in disguise, and scammers print their own codes on stickers, flyers, parking meters, and fake emails. The safest move is to check where a code goes before your phone opens it.

Three quick tells that a code is risky

  • It's a sticker placed over the original (peel-and-stick scams are everywhere on parking meters and menus).
  • It arrives in an unexpected text or email — a "missed delivery," "toll due," or "account locked" message.
  • Scanning it asks you to log in or pay right away on a page that looks a little off.

The reliable fix is to preview the destination before you commit. That's exactly what ScanLikely does — it reads the code and flags a bad link, fake payment screen, or unsafe WiFi network before it can load.
