# How do you read a QR code? There are several factors that influence whether a person or potential customer can read a QR code, but without a doubt, the most important factor is that the individual who wants to scan the code needs to have a mobile phone. Nowadays, there are many mobile devices that can read QR codes with the camera itself, by simply pointing the camera at the code to scan it. If this doesn't work, you may need to download an application designed to read QR codes. But don't worry! There are several apps that do just this. We also have our own QR reader that is free to use for everyone, [check it out here](https://sqr.co/qr-reader). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
