Let me explain what I'm trying to do, and then where I am at...
As you can see on this image :
There is a PDF417 at the end containing a string that at my best guess is some base64 string.
Here it is :
And when I decode it, I get the following :
I kind of found the waitress name "Julie" and in front of it, there is a bunch of space characters, which I guess it is because there is a limited size to the name.
Same for the bill number, and the table number.
But I was wondering what kind of information was in the previous bits, so any idea how to proceed to decode/decrypt this information would be greatly appreciated.
The machine used for the generation of the base64 string and its content is a "AEC-6822".
And here is some unrelated information to what I'm trying to do, but may help... (I hope) http://www.revenuquebec.ca/documents/en/publications/in/in-577-v(2013-08).pdf
Thank you very much, ANY help is greatly appreciated!
