I have a "code39" barcode. How can I get the information from that bar code: product name, manufacturer, and everything else?
Please help.
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.
