barcode - 如何获取“Code39”条码信息？

Question

我有一个“code39”条形码。如何从该条码中获取信息：产品名称、制造商和其他所有信息？

请帮忙。

Answer 1

Find a bar code scanner that reads code 39 encoding--which is just about all of them, and scan the bar code. That number will normally be a GTIN - Global Trade Item Number. You will have to use that number and query some kind of database or web api to get the rest of the product data.
