推荐答案

好的，所以你我需要一个数据库，其中包含您想要与该条形码相关联的所有信息。



如果您在谈论几乎所有产品的条形码在商店货架上发现它在美国被称为UPC或通用产品代码。有数据库，但没有一个完全免费。

OK, so you're going to need a database that has all the information you want associated with that barcode.

If you're talking about the barcode you find on just about every product found on store shelves its called a "UPC" or "Universal Product Code" in the US. There are databases out there, but none of them are completely free.
