User Guide
Get started with OneScan in just a few easy steps. Enjoy a seamless, secure, and modern QR code experience!
Enter Your URL

Your URL must start with HTTPS, not HTTP.
For your security, OneScan only accepts links that begin with https://. This ensures your data is always encrypted and protected from the start.
Any link that does not use HTTPS will be rejected by the app. This is a key part of our commitment to your privacy and safety.
Get Your QR Code

Once you have entered a valid HTTPS link, simply click the Generate QR Code button below the input box.
OneScan will instantly check your link and, if valid, create a unique, one-time QR code just for you.
This step is fast and secure your QR code is never reused and is always protected.
View & Save Your Secure QR Code

After generating, your one-time, secure QR code will appear on the screen.
This code can only be scanned once, making it perfect for sharing sensitive links or information safely.
To keep your QR code, tap the Save in Gallery button. This will store the QR code image directly to your device's photo gallery for easy access.
Find Your QR Code in Gallery

Open your device's photo gallery. You will see your newly saved QR code image, ready to use or share at any time.
This makes it easy to retrieve your code whenever you need it, even offline.
With OneScan, your QR code is always just a tap away secure, private, and under your control.
