# QR codes & QR markers

> A QR code opens a hotspot when scanned, while a QR marker shows where the QR code is located on a photo.

## Overview

ObservV uses QR codes to connect a physical location on site with the matching hotspot in the platform.

* **QR code.** A physical code placed on site and assigned to a hotspot. When someone scans it, ObservV opens the linked hotspot. Access still follows ObservV permissions.
* **QR marker.** A marker placed on a photo to show where the physical QR code is located on site.

QR code actions are managed from the hotspot. QR marker actions are managed from the photo using **Photo QR actions**.

QR markers help people find QR codes in the real environment and check that the physical code is still present, visible, and correctly positioned.
