HOW COMW WHEN I CHANGE THE DATA AND GENERATE A FAKE IOWA PDF417 CODE MY READER AT WORK I GET A FAILED SCAN MESSAGE BUT WHEN I USE ANOTHER PDF 417 FROM A DIFFERENT STATE IT WORKS JUST FINE IS THERE A DIFFERENT OUTPUT FORMAT OPTION THAT I AM UNAWARE OF.

Hi, great video! Do you know, if there is some mathematical definition of PDF417 Codeword Combos or every de/encoding device has to have the whole table saved somewhere?

Is there something that I can use to read this raw data? A scanner. Most scanners just give you the info not the raw code

Good presentation. Where do we find the list of Codewords?

Hi, Is there is an online reader that can just give me the codes without translating them. I really want to see the raw data of every word. I want to see specially what is in the first column and the last column. and thank you for this great tutorial. I believe it is the only one on the internet that goes step by step. Thanks

I was strangely uncomfortable hearing him go "We have three blacks, one white, two blacks..."

Why is this coded in unary? That's so inefficient.
