How to Get Rid of QR and Barcode Scanners
Learn how to safely disable or remove QR and barcode scanning on smartphones and desktops, with platform-specific steps, privacy-focused tips, and safer alternatives.
To get rid of QR and barcode scanners, you’ll disable or remove scanning features on devices, revoke camera permissions for apps with scan capabilities, and deploy controls to block scan across apps. This guide uncovers platform-specific steps, safety considerations, and practical fallbacks to preserve usability while reducing risks. It also outlines testing steps and recovery tips.
Why removing QR and barcode scanners may be desirable
In many homes and workplaces, QR and barcode scanners are handy technologies. However, there are privacy, security, and usability reasons to consider removing or disabling them. For parents managing children's devices, turning off scanning helps limit exposure to phishing or malicious codes. In a corporate setting, scanning can create data leakage risk if codes are attached to sensitive inventory or access credentials. This guide explains practical methods to minimize or eliminate scanning features without compromising essential functions.
How QR and barcode scanning works on devices
Most scanning functions rely on the device camera and software libraries to interpret patterns on codes. On smartphones, many platforms treat QR codes and barcodes as “special codes” that can trigger actions like opening a URL or revealing product data. Some devices expose a built-in scanning mode inside the camera app, while others rely on third-party apps. Understanding where scanning comes from helps you decide which controls to apply.
Assessing your environment: where scanning can occur
Scan functionality can appear in multiple places: native camera apps, dedicated scanner apps, browser extensions, and sometimes in enterprise inventory tools. Start with a quick inventory: list apps with camera permissions, check browser permissions for websites, and note any enterprise management software that may enforce scanning capabilities. This awareness reduces the risk of inadvertently re-enabling scanning later.
Android-specific steps to disable scanning
- Open Settings > Apps & notifications, and review camera permissions. Revoke camera access for apps that offer scan features.
- Uninstall or disable any scanner apps you no longer need.
- Use Family Link or a corporate MDM to block camera access for groups of apps if you manage a family or business device. Tip: After changes, reboot the device to ensure permissions refresh and scan calls are blocked.
iOS-specific steps to disable scanning
- Open Settings > Screen Time > Content & Privacy Restrictions > Camera and turn it off for specific apps, or globally if your policy allows.
- Use Guided Access to lock devices to a single app during use, preventing access to other apps that might enable scanning.
- If you manage multiple devices, deploy a configuration profile via MDM to disable camera access for scanning apps. Tip: Test by attempting to scan a code after changes to verify the restriction is effective.
Web and browser controls to curb scanning
Many scanners can be triggered by browser-based previews or websites requesting camera access. In browsers, revoke or block camera permissions for sites you trust least and deny permission to all sites for scanning. Using browser profiles for work and personal use can isolate scanning permissions. Keep in mind that some sites implement server-side scanning; this block should focus on client-side control.
Enterprise and parental controls for families and organizations
MDM solutions allow admins to disable hardware features, including the camera, or restrict apps that provide scanning functionality. For families, use built-in parental controls to restrict app installations or set time limits that reduce scanning opportunities. Document changes and keep an up-to-date inventory of allowed apps to prevent accidental re-enabling.
Safer alternatives when you need to input data manually
If you disable scanning, you may still need to enter data like product IDs or URLs. Use copy-paste, manual entry, or offline codes printed on documents. Maintain a safe fallback process and provide training for users to ensure accuracy when manual entry is required. This reduces reliance on scanning while preserving productivity.
Testing and validation after changes
After applying settings, test on all major apps and websites you use. Try scanning a QR code with the camera to confirm it no longer triggers the expected action. Check that legitimate camera-dependent features, like video calls or document scanning apps that you still use, remain functional. Keep a log of tests and outcomes for accountability.
Common mistakes and how to avoid them
- Forgetting to revoke permissions in all apps that can scan; re-check after updates.
- Blocking the camera globally but not testing with critical apps; always test business workflows.
- Overly narrow controls that still allow scanning through embedded web apps; block at the browser level as well.
Final considerations on privacy, security, and usability
Disabling QR and barcode scanners can strengthen privacy and reduce risk, but it may impact workflows that rely on quick data capture. Balance controls with usability by offering safe, manual alternatives and clear user guidance. Regular audits help ensure scanners stay disabled as new apps or updates appear.
Tools & Materials
- Device with camera access(Phone, tablet, or laptop with working camera)
- OS version knowledge(Note the exact Android or iOS version to tailor steps)

- Password or admin credentials(Needed for some settings or profile installs)
Steps
Estimated time: Estimated total time: 25-45 minutes
- 1
Identify sources of scanning
Audit your device to identify all sources of QR/barcode scanning: built-in camera modes, installed scanner apps, and any browser extensions. Create a quick list to guide the changes.
Tip: Use a simple app-permission scan in Settings to start the inventory. - 2
Review and revoke camera permissions
Go through each installed app and revoke camera access for those that provide or request scan capabilities. Leave permissions only for apps you truly need to capture images.
Tip: If a change breaks a necessary app, re-evaluate its necessity or switch to manual data entry. - 3
Uninstall or disable scanner apps
Remove third-party scanner apps you no longer use. If you must keep some apps, disable their scanning features rather than uninstalling to preserve other functionalities.
Tip: Reboot after uninstall to ensure changes take effect. - 4
Apply system-level controls
Use Screen Time (iOS) or Family Link/MDM (Android) to limit camera use or block categories of apps. For organizations, deploy a configuration profile to enforce restrictions.
Tip: Document the policy so users know what to expect. - 5
Test the restrictions
Attempt to scan codes across apps and websites to verify that scanning no longer triggers actions. Check a few common apps (messaging, shopping, etc.) for unintended behavior.
Tip: Keep a test log for accountability. - 6
Maintain and monitor
Schedule periodic reviews of app permissions and device policies to catch new scanning sources as apps update or new ones install.
Tip: Set a quarterly reminder to review controls.
Common Questions
Can I completely disable QR and barcode scanning on my smartphone?
Not always. Built-in camera scanning and some system services may continue to offer scan-like functionality. You can disable or restrict access via permissions and settings, but some devices may still offer minimal scanning in limited contexts.
You can usually restrict or disable most scanning features, but some built-in capabilities may remain. Check your device settings to limit access and test after changes.
Will disabling scanning affect other camera apps?
Revoke camera permissions selectively for scanning apps to minimize impact. Other apps that use the camera for calls or photos will be affected only if you remove camera access entirely. Re-enable selectively if needed.
Revoke permissions for scanning apps, but leave camera access enabled for essential apps like video calls.
Is it safe to disable scanning on work devices?
Yes, with IT coordination. Use MDM or enterprise policies to enforce restrictions and document changes so workflows aren’t disrupted.
Yes, as long as IT approves and you implement it through official management tools.
What about web-based QR codes and browsers?
Block camera permissions for browsers and enforce policy at the browser level. Some sites still process scans server-side, but client-side scanning will be restricted.
Blocking browser access to the camera helps stop web-based scanning.
What are best practices to maintain usability after disabling scanning?
Provide manual data-entry alternatives, document changes, and train users. Schedule periodic audits to catch new scanning apps.
Offer manual entry options and keep a clear audit trail so usability remains stable.
