Before clicking the pop-up link, look at the URL preview. Does it look like the official website?
In 2026, downloading a QR code reader is largely a thing of the past. Unless you have a specific professional need for data logging or are using an ancient device, save your storage space and stick to the built-in features you already own.
You can also add a dedicated "Code Scanner" button to your Control Center via Settings for even faster access. For Android Users
Snapchat, TikTok, and WhatsApp all have built-in scanners (usually found in the search bar or "Add Friends" section) that can read standard web URL QR codes.
Never enter credit card info on a site reached via a QR code unless you are 100% certain of the source.
