Product Barcode Knowledge

A product barcode is an internationally unified code used to identify a product, acting like its "ID card". The most common product barcode is the EAN-13 code, consisting of 13 digits, which includes the country code, manufacturer code, product code, and check digit. By scanning the barcode, products can be quickly identified, inventory managed, and sales settled, greatly improving the efficiency and accuracy of commercial circulation. It is an indispensable part of modern retail and logistics systems.

Frequently Asked Questions

• Q: What barcode types are supported? A: This tool primarily supports international product barcodes, such as EAN-13, UPC-A, and other standard code systems.
• Q: What are the specific requirements for uploading images? A: Please upload PNG or JPG format images, with a single image size not exceeding 5MB. The barcode in the image must be clear, complete, free of reflections or obstructions, and kept as horizontal as possible to improve recognition success rate.
• Q: Why can't I find results or why are the results inaccurate? A: Please check if the entered barcode number is correct, or if the uploaded image is clear enough. Some product information may not be found due to delayed database updates or the product itself not being recorded.
• Q: What is the purpose of the image scaling function? A: The image scaling function helps users adjust the size of uploaded images. Sometimes, appropriate scaling (especially reducing overly large images) can optimize image processing speed and recognition results, but it is not always necessary to adjust.

Notes

• Please ensure that the entered product barcode number is accurate to avoid query failure or result deviation due to incorrect input.
• When identifying via image, the clarity, completeness, and placement angle of the barcode directly affect the recognition success rate.
• The product information provided by this tool comes from public data and is for reference only, not as official proof. Actual product prices, specifications, and other information should be based on official releases or actual purchases.
