Hi! We have to talk about the architecture of our solution.

I've seen what Spartan proposes. I trhink it's ok to follows the requirements, but, we can use the card service

http://pyscard.sourceforge.net/pyscard-usersguide.html#cardcentric

Btw, i found (0e2a2a3596) why the card request does not work : Wrong ATR.

To get the ATR, see /usr/share/doc/python-pyscard/examples/Examples/framework/sample_CustomCardType.py (if you installed pyscard using the debian package. The file can alternatively be found at: http://pyscard.svn.sourceforge.net/viewvc/pyscard/trunk/pyscard/src/smartcard/Examples/framework/ )

Hi! Actually I also tried the commented piece of code with card type "AnyType" and it didn't work either. Since pcsc_scan is not able to detect any card either on my laptop, I assumed either my installation has a problem, or the ACR122 reader needs to do polling to detect a card. By the way, if it works for you, we can use the card centric approach.

err.. looks like your problem with the reader is back... the pcsc_scan command should detect your reader.

spartan05 commented 12 years ago

The pcsc_scan command is able to detect my reader but it should also detect cards in the range of the reader and print a line when it occurs. This doesn't work on my laptop. Does it work for you?

opened https://github.com/nimai/Project-BITCH/issues/4 for this

there is also the possibility of using an observer like in sample_MonitorCardsAndTransmit.py
