3 Ways to Scan QR Codes from Photos or Documents
QR codes have been around for more than two decades, but it is relatively recently that they have become an integral part of our lives.
From restaurant menus to product labels, event tickets, and business cards, these small, square patterns provide a quick gateway to information and resources.
While scanning a QR code directly from a screen is a familiar experience, what if you stumble upon one in a photo or document?
No worries - We'll explore various methods to show you how to scan QR codes from photos and documents, making it easier than ever to access the information they hold.
Let’s dive in!
What are QR Codes?
QR codes, or Quick Response codes, are two-dimensional barcodes that store information in a pattern of black squares and white spaces.
Since their invention in 1994, they’ve become widely used for various purposes due to their ability to efficiently store and quickly retrieve data.
In addition, you can scan them with smartphones, tablets, or dedicated QR code scanners.
How Do QR Codes Work?
The way QR codes work takes 4 stages:
1. Encoding Information
QR codes can store different types of data, such as text, URLs, contact information, Wi-Fi network credentials, etc.
The data is encoded into the QR code's pattern of black and white squares using a specific encoding method.
2. Scanning
To access the information stored in a QR code, you need a device with a camera and a QR code scanning application.
Luckily, most modern smartphones come with built-in QR code scanning features in their camera apps.
Thus, when you scan a QR code with your device, the camera captures the code's pattern, and the QR code scanning app or feature decodes the data.
3. Decoding
The decoding process involves recognizing the patterns of squares and spaces, interpreting the data, and converting it into a usable format.
For example, this may involve extracting a URL, text, or other information, depending on what the QR code represents.
4. Action or Display
Once the data is decoded, the device typically offers options on how to proceed. For example, if the QR code contains a URL, your device may prompt you to open a web page associated with that URL.
On the other hand, if it includes contact information, it may allow you to add that contact to your address book. The action depends on the type of data encoded in the QR code.
Which Industries Benefit Most from QR Codes?
QR codes have various purposes, such as in:
- Marketing - QR codes are on product packaging, advertisements, and promotional materials, providing a quick way for customers to access product information or discounts.
- HoReCa - You can use QR codes to inform customers about hotel and restaurant catering and menus.
- Contactless Transactions - You can use QR codes for making mobile payments, connecting to Wi-Fi networks, or accessing event tickets.
- Information Sharing - QR codes can store contact details, event details, etc., making it easy to share this information with others.
- Authentication and Security - You can use QR codes in two-factor authentication processes, helping to enhance security.
- Inventory and Tracking - Businesses use QR codes to track inventory and manage products.
- Navigation - QR codes can contain geospatial coordinates or map links to provide location information and directions.
And now, let’s finally see how to scan QR Codes from photos or documents.
How to Scan QR Codes from Photos or Documents in 3 Easy Ways?
1. How to Scan a QR Code with Google Lens?
The main reason we start with Google Lens is because it works on both iOS and Android devices.
Most newer generation phones come with an in-built Google Lens, but even if you don’t have it, you can easily download it from the Play Store.
Step 1
Tap on the Lens icon in the search bar, and the images on your phone will appear.
Step 2
Once you’ve found the image with the QR code, Google Lens will scan it and show the information.
Step 3
You just need to click the link to be redirected to the website or another destination.
2. How to Scan a QR Code From iOS Devices?
With iOS devices, you can scan QR codes right from your photo gallery in a few simple steps:
- Open the image in your photo gallery.
- Click The Live Text Detection button at the bottom right corner and tap the QR code.
- The Live Text feature scans the QR code and offers multiple options: to open the link in a browser, share it with others, copy the link, etc.
3. How to Scan a QR Code Using Third-Party Apps?
Along with the above mentioned methods, you can use third-party apps to scan QR codes.
And if you wonder why you’d go for them if you can use the already built-in tools, here are the key reasons why you might opt for third-party apps.
✨ Enhanced Features - Third-party apps often come with additional features and customization options that may not be available in built-in scanning apps.
✨ Speed and Accuracy - Some third-party apps use more advanced algorithms for improved performance.
✨ Compatibility - Available on a broader range of devices and operating systems.
✨ Extra Functionality - Certain third-party apps can scan not only QR codes but also other types of barcodes like UPC, EAN, etc.
✨ Privacy and Security - Some third-party apps offer privacy features that allow you to control what data is shared when scanning QR codes.
✨ Offline Mode - Some of the apps offer offline functionality, which can be handy when you need to scan codes in areas with limited or no internet connectivity.
Although the scanning process may differ depending on the app, this is how it goes in general:
Step 1
Open the app and select the Scan, QR Scanner, or some similar option.
Step 2
You need to grant camera permissions for the app to access your device's camera.
Step 3
Point your camera at the desired QR code and wait for a scan.
Step 4
Once the app scans the code, you’ll get options to open the link, share it, etc.
Many QR code scanning apps have a scan history, allowing you to see previously scanned QR codes.
Wrapping It Up
Whether you should use a third-party QR code scanning app or a built-in one depends on your specific requirements and preferences.
If the built-in scanner meets your needs and you value native integration and simplicity, it might be the best choice.
However, if you require extra features and customization or have specific privacy concerns, a third-party app might be more suitable for you.
And although choosing the optimal third-party app might be a difficult task, for us, the choice is simple.
Our choice will always be Tapni.
