Detection of country/network code fail reading Italian venice transport operator #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. hard code row data I wrote below
2. try to read country code and network code..
3.

What is the expected output? What do you see instead?
expected output should be 330 but I get "nil"

What version of the product are you using? On what operating system?
latest svn

Please provide any additional information below.

The script uses an heuristic method to find the country code. Apparently it 
doesn't work with the Italian Venice transport operator data. I'm not sure I 
can fix this.

I also have a problem reading the country code on the Israeli calypso transport 
card (RavKav).
calypso.lua does this:
    country_bin = bytes.sub(data,13,24)
    network_bin = bytes.sub(data,25,36)
but the Israeli Calypso Spec says:
    version     = bytes.sub(data,0,2)
    country_bin = bytes.sub(data,3,14)
    issuer_id   = bytes.sub(data,15,22)
    app_number  = bytes.sub(data,23,48)
    ...etc.
So the country code is at a different offset!

This is unfortunate. I was hoping that the country code would be always at the 
same place, as was verified on French and Belgian cards. I guess that detecting 
the card country is going to be more complicated than I was hoping. Perhaps I 
will have to rely on the ATR or something.

Would you have the specs of the RavKav card to share with me <L1L1 _at_ 
gmx.com>? Perhaps I can figure out something form them.

I will close this issue since the network detection algorithm has changed a lot 
in Cardpeek.
If I get access one day to the specs of the venice transport card, we might be 
able to add it to cardpeek.
