Decoding 2D barcodes

Decoding 2D barcodes

Decoding 2D barcodes

(OP)
Hello all;

I'm trying to get a Symbol DS6707 to decode a 2D barcode (like the one on the back of some drivers licenses) but have hit a snag.  Some of the bar codes decode just fine.  Others seems to send ALT key combos that make programs like note pad want to save the document.  I'm not sure if its sending a ATL-S or ALT-A or ALT-F4 but its sending something strange.  Has any one else seen this sort of thing and know how to fix it?

RE: Decoding 2D barcodes

Barcodes may have all sorts of data encoded in it; sometimes this data is not visible in the scan. You may want to use an ASCII Decoder (it's free), an application that displays hidden characters:

You will get a better idea as to what is exactly in the barcode.



 

RE: Decoding 2D barcodes

I suspect that the data in some of these barcodes is probably encrypted.

... so your scanner just returns some encrypted characters, each of which could potentially be ANY character, depending on the encryption.
