Have you ever noticed those black and white vertical lines with accompanying numbers on product packaging? That’s a barcode, a simple yet powerful tool for storing specific data like product codes, expiration dates, or identification numbers. Barcodes are widely used in various industries because scanning them is quick and efficient.
Interested in learning more about barcode scanning, especially on your Android phone? This article will guide you through everything you need to know, from understanding what barcodes are to mastering different scanning methods on your Android device.
What is a Barcode?
A barcode, short for bar code, is essentially a visual representation of data that machines can read. As mentioned by eprints.polsri.ac.id, it’s a code often printed on stickers or directly onto product packaging. Visually, a barcode is composed of a series of vertical black and white bars of varying widths.
While commonly associated with retail shopping, barcodes are versatile and used across diverse sectors. Beyond the lines themselves, barcodes also include numbers that provide further information about the product. These numbers are structured with specific components:
Number System Character (NSC)
The Number System Character (NSC) is a digit within the UPC (Universal Product Code) barcode system that indicates specific categories or attributes of the barcode. UPC is predominantly used in industries, especially in North America. In a UPC barcode, the NSC is typically the leftmost digit. Here’s what each number signifies:
- 0: Standard UPC number
- 1: Reserved for future use
- 2: Random weight items (like produce or meat sold by weight)
- 3: Pharmaceuticals
- 4: In-store code for retailers (often for variable measure items)
- 5: Coupons
- 6: Standard UPC number
- 7: Standard UPC number
- 8: Reserved for future use
- 9: Reserved for future use
Guard Bars
Barcode structure includes three guard bars: located at the beginning, middle, and end of the code. The start and end guard bars are represented as “bar-space-bar” or “101” in binary terms. The middle guard bar is represented as “space-bar-space” or “01010”. These bars help scanners properly read the barcode.
Manufacturer Code
The Manufacturer Code is a five-digit number that uniquely identifies the product’s manufacturer. This code is assigned and protected by the Uniform Code Council, ensuring each company has a distinct identifier.
Product Code
Following the Manufacturer Code, the Product Code is another five-digit number. This code is assigned by the manufacturer to each specific product they produce, differentiating items within their product line.
Check Digit
Positioned at the far right of the barcode, the Check Digit is crucial for validation. This digit is mathematically calculated from the preceding digits and ensures the barcode has been scanned accurately. It helps prevent errors during data entry.
Benefits of Barcodes
Barcodes offer numerous advantages, particularly for businesses. Here are some key benefits:
1. Faster Transaction Processing
Printing barcodes directly on products significantly speeds up data input compared to manual methods. Scanning eliminates the need for manual typing of product codes or numbers during transactions, making checkout lines move faster and improving customer satisfaction.
2. Improved Data Accuracy
Barcode scanning is not only faster but also more accurate than manual data entry. This reduces errors in pricing, inventory, and sales records. Improved accuracy leads to better inventory management, fewer pricing mistakes, and more reliable sales data for analysis.
3. Versatile Applications
Barcodes are not limited to retail product labels. They are used in a wide array of applications, including book publishing (ISBN barcodes), non-retail sectors, pharmaceutical identification for medications, asset tracking within organizations, inventory management in warehouses, laboratory data management, and even on identification cards and membership cards. Their adaptability makes them a valuable tool across various industries.
4. Cost Reduction
Barcodes are an economical solution due to their simplicity and low implementation costs. The materials needed – paper and ink – are inexpensive. Barcode scanners are also readily available and relatively affordable. This cost-effectiveness makes barcodes accessible for businesses of all sizes looking to improve efficiency without significant investment.
How to Scan Barcodes on Android Phones
Scanning barcodes on your Android phone is surprisingly easy, and there are several convenient methods you can use. Let’s explore the most common ways:
Using Your Android Camera App
Many modern Android phones have integrated barcode scanning capabilities directly into their default camera app. This is often the quickest and easiest method.
-
Open the Camera App: Launch the camera application on your Android phone, just as you would to take a photo.
-
Point at the Barcode: Position your phone’s camera so that the barcode is clearly visible within the viewfinder. Make sure the barcode is well-lit and in focus. The phone’s camera should automatically detect the barcode.
-
Barcode Detection: Once detected, your camera app may display a visual cue, such as a highlighted box around the barcode, or a small pop-up notification.
-
Open the Link/Content: Tap the pop-up notification or the highlighted area. This will typically open a link in your web browser if the barcode contains a website URL, or display the encoded information directly on your screen. The specific action will depend on the type of barcode and your phone’s software.
Scanning Barcodes with Google Assistant and Google Lens
Google Assistant offers a powerful feature called Google Lens, which can recognize and scan barcodes, QR codes, and much more.
-
Launch Google Assistant: Activate Google Assistant on your Android phone. This is usually done by long-pressing the home button or swiping up from the bottom corners of your screen, depending on your phone’s navigation settings. You can also open the Google Assistant app directly if you have it installed.
-
Access Google Lens: Within the Google Assistant interface, look for the Google Lens icon. It typically resembles a square with a dot inside. Tap on this Lens icon to activate the visual search feature.
-
Grant Camera Permissions (if prompted): If this is your first time using Google Lens, you may be asked to grant permission for Google Lens to access your phone’s camera. Allow the necessary permissions to proceed.

Point at the Barcode: Aim your phone’s camera at the barcode you want to scan. Google Lens will automatically recognize the barcode.
-
View Results: Once the barcode is scanned, Google Lens will display the information encoded in the barcode directly on your screen. If the barcode contains a URL, you’ll see a link you can tap to open in your browser. For product barcodes, Google Lens might show product information, reviews, and shopping options.
Scanning Barcodes Using a Browser
You can also scan barcodes directly through your web browser using online barcode scanner websites. This is a useful alternative if your camera app doesn’t have built-in scanning or if you prefer using a web-based tool.
Using Google Search
Google Search itself provides a barcode scanning function within its search bar on mobile devices.
