Hi there! I see you're having trouble initiating the scanner on the Vemos app on your iPhone running iOS 18.5.0. I'd be happy to help you get that sorted out.

To start, could you tell me a bit more about what exactly happens when you try to start the scanner? For example:
- Does the app give you any error message?
- Does the scanner view open but the scanning doesn’t work?
- Is the camera permission granted to the app?

Knowing this will help me narrow down the issue.

In the meantime, here’s a general step-by-step to troubleshoot the scanner feature:

1. Check Camera Permissions:
- On your iPhone, go to Settings > Privacy & Security > Camera.
- Make sure that Vemos app is allowed to access the camera. If it's off, turn it on.

2. Restart the App:
- Swipe up from the bottom of the screen (or double press the Home button if you have one) to open the app switcher.
- Swipe Vemos app away to close it.
- Reopen the app and try the scanner again.

3. Restart Your Device:
- Hold down the power button and volume button, then slide to power off.
- Turn your iPhone back on and retry the scanner.

4. Update the App:
- Open the App Store, tap your profile icon up top.
- Scroll down to see if there's an update available for Vemos app and install it.

5. Check Network Connection:
- Sometimes the scanner needs internet to verify IDs.
- Make sure your Wi-Fi or cellular data is active and strong.

6. Reinstall the App:
- If none of the above works, try deleting the app and reinstalling it from the App Store.

If you could tell me which of these you’ve already tried or what behavior you see when you hit the scanner, we can zero in further on the solution.
Are you comfortable trying these steps, or would you like me to guide you through any of them?
