在应用程序列表中就能找到应用商店，比如Google Play。它的图标看起来像一个购物袋，上面有Google Play的标志。

它位于应用商店界面的顶部。

其他类似的扫描程序也有很多，你可以多尝试几个。大多数的功能差不多。

如果部分或全部条码太暗，扫描程序会很难识别。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/7\/79\/Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-10-Version-2.jpg\/v4-460px-Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-10-Version-2.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/7\/79\/Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-10-Version-2.jpg\/v4-728px-Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-10-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

确保整个方形二维码都在手机屏幕上的方框内。

扫描传统的条形码时，取景框中的线要与条形码的线垂直。
{"smallUrl":"https:\/\/www.wikihow.com\/images_en\/thumb\/a\/ac\/Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-12-Version-2.jpg\/v4-460px-Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-12-Version-2.jpg","bigUrl":"https:\/\/www.wikihow.com\/images\/thumb\/a\/ac\/Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-12-Version-2.jpg\/v4-728px-Scan-Barcodes-With-an-Android-Phone-Using-Barcode-Scanner-Step-12-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"<div class=\"mw-parser-output\"><\/div>"}

如果条码看起来比较模糊，调整距离有助于聚焦。

扫描成功后，会感觉到手机震动并听到哔哔声。

二维码包含各种不同类型的链接和内容。传统的条形码只包含一组数字。如果某件产品很受欢迎，那么这个数字可能就跟该产品有关。如果这个条形码是专为某家商店或其他当地商店而生成的，那它很可能只是一些对你没什么意义的数字而已。

小提示

传统条形码一般只包含基本的标识信息，商店会用这些信息在自己的数据库中查找详细信息。也就是说，你无法扫描商店里的商品并查看价格或其他任何详细信息。最多只能在网络搜索中通过产品编号找到某样产品。

警告

点击二维码中的链接时要小心。有些人可能会在看似无害的条码里附带恶意链接的标签。
