Hi,
at first thanks for your great effort to write this library! I just installed it and it works like a charm. However I noticed a minor missmatch to a website I found.
For the GRAI-170 Tag from your tests I found that
decode_epc("0x37012a05f20000188000000000000000000000000000").barcode == '8003032000000000011' decode_epc("0x37012a05f20000188000000000000000000000000000").values['serial_number'] == '1'
With a serial number of '1' the second last digit is the check digit which is '1'.
When inserting this to http://convert.erfideo.com/Home
all values but the check digit (which is 9 on this website) does match.

May you explain weather the website yields wrong values or this a bug in the code?

Many Regards
Dennis

Edit1: Additionally the convert.erfideo.com truncates the epc_hex by one trailing '0'. Why are there different lenghts?
