Thanks for the reply, but the barcode consists of an EAN13 code and a small distance from a code of EAN5. Italian newspapers have this dual code that locates the newspaper (EAN13) and the date of publication (EAN5). The double code should be read in a single step. In annex I reproduce an example of

To confirm, just in case: The bar code construction is fine; the issue is what preference your barcode scanning libraries or apps have when they scan a barcode that is validly more than one barcode type. Your barcode: 135906 is both valid EAN-13 and valid UPC-A. It is impossible to tell from the

I figured it out! Since the option "Barcode" was in the position of No ( Wait For (ThirdDialog.ShowTemplate(input3, "RF", "Barcode", "")) complete (result As Int)), the program executed the code without reading the input. When i changed the order and placed the "Barcode" option to the position of

This is a good example of barcode reading: https://www.b4x.com/android/forum/threads/b4x-b4xpages-barcode-reader.120417/ It doesn't split the parts. I'm not an expert in this, however I'm not sure that the spaces or parts are actually encoded in the barcode.

I use barcode readers all the time we set our barcode reader to append a character to the end of the scanned data. That way we know an entire barcode has been read or alternately one has been typed in. Its very easy to add a suffix character when setting up the scanner.

link: It can also be a good idea because the barcode reader adds a chr(13) at the end. However, when the user types then there is no such chr(13). Thank you
