How Barcode Scanning Works

Camera Scanning

Your device's camera captures live video. The scanner analyzes each frame in real time to detect and decode barcodes, using your device's built-in detector where available for speed. Works best with good lighting and a steady hand.

Image Upload

Upload a photo containing a barcode and the scanner reads any barcode it finds. Great for screenshots or saved images. Decoding happens locally on your device.

1D Barcodes

Traditional linear barcodes like UPC, EAN, Code 128, and Code 39. Found on retail products, shipping labels, and inventory systems.

2D Barcodes

Matrix codes like QR Code, Data Matrix, and PDF417. Can store more data including URLs, text, and contact information.

常见问题

这个条形码扫描器免费吗?

是的,完全免费且扫描次数不限。条形码解码完全在浏览器中完成。当您打开商品链接时,仅发送已解码的条形码号码以查找匹配商品。

为什么摄像头不能用?

请确认已在提示时授予摄像头权限。摄像头访问需要安全(HTTPS)连接。请尝试 Chrome 或 Safari,确保没有其他应用占用摄像头,并用“翻转摄像头”在前后摄像头之间切换。也可以手动输入条形码号码。

支持哪些条形码类型?

支持主要格式:UPC-A、UPC-E、EAN-13、EAN-8、Code 128、Code 39、Code 93、Codabar、ITF、QR Code、Data Matrix、Aztec Code 和 PDF417。可用格式可能因设备和浏览器略有不同。

如何提高扫描效果?

光线充足、条形码保持稳定、尽量放平(不要弯曲)、让条形码占满大部分画面,并避免反光。如果模糊,可将设备稍稍远离以便对焦。

我的数据是否私密安全?

摄像头画面和上传图片仅在您的设备本地处理,不会上传到服务器。扫描历史只存在浏览器中,可随时清除。我们可能收集基本匿名使用分析,例如扫描方式、条形码格式、结果类型、查询结果和外链点击。原始条形码值不会发送到 Google Analytics。
