How to Scan Unscannable Barcodes: Tips and Techniques
Scanning unscannable barcodes can be a frustrating task. However, with the right approach and tools, you can significantly improve your chances of successfully reading these codes. Here are detailed steps and techniques to help you:
Understanding Why a Barcode Might Be Unscannable
The inability to scan a barcode often depends on various factors. Many scanners are designed to read specific types of barcodes and are not equipped with the necessary hardware or firmware to process others. Additionally, some barcodes may be outdated or damaged, making them challenging to read. Before proceeding, it's essential to understand why the scanner is struggling to read the barcode.
Improving Lighting Conditions
Avoid Glare
Ensure the barcode is not reflecting light, which can obscure the code. Avoid areas with direct sunlight or bright, reflective surfaces.
Use Soft Lighting
Good, diffused lighting can help the scanner read the barcode more effectively. Avoid harsh, direct light sources that may cause glare or shadows.
Adjusting Scanner Settings
Ensure Proper Focus
Proper focus is crucial for the scanner to read the barcode accurately. Adjust the focus on the scanner to ensure it is centered on the barcode.
Experiment with Distance
Some scanners work better at specific ranges. Experiment by trying different distances to find the optimal position for scanning.
Adjust the Scanning Angle
Change the angle of the scanner to find the optimal position for scanning. Sometimes, a slight adjustment can make a significant difference.
Using High-Quality Scanners
Invest in a high-quality barcode scanner that can handle damaged or low-contrast barcodes. Consider using mobile apps like ZBar, which can read barcodes that standard scanners might struggle with.
Enhancing the Barcode
Improve Contrast
Print the barcode with higher contrast, ensuring darker bars and a lighter background. This helps the scanner read the code more easily.
Repair or Replace the Barcode
If the barcode is damaged, consider printing a new label or using software to recreate it. This can significantly improve readability.
Manual Entry as a Fallback
If you can read the barcode numbers, you can manually enter them into your system. Alternatively, use the product or item number associated with the barcode to find it in your database.
Utilizing Barcode Decoding Software
Image Processing
Use software that can analyze images of barcodes and decode them, even if they are damaged or blurred. This is particularly useful for 1-D barcodes where the least-damaged part of the barcode is scanned.
OCR Technology
Optical Character Recognition (OCR) tools can sometimes read barcodes from images, especially for 2-D barcodes with redundant information for error correction such as QR codes and Data Matrix.
Seeking Professional Help
If the barcode is critical to your operations, consider consulting professionals who specialize in barcode scanning and printing. They can provide expert advice and solutions to ensure accurate and efficient barcode reading.
Conclusion
While unscannable barcodes can be a significant challenge, employing a combination of these strategies can significantly improve your chances of successfully reading them. By understanding the underlying issues and using the right tools and techniques, you can streamline your barcode scanning processes and avoid frustration.
