Notes, Readers and Drivers Setup
Following demos show various use of Waver in tutorial, step by step form.
Focus is on user scenarios ("how it can be done"), not on proper
implementation of all security mechanisms,
which can be found in textbooks or in another 3rd party examples/projects.
reader is accessed directly from Web Browser with the
help of CPA (Card Proxy Applet), i.e. it is neccessary
These demos have been tested with various operating systems
and browsers, notably MS Windows with Explorer and Firefox
and Linux Fedora 8 (with default PC/SC v1.3.3 and Firefox).
As for readers we recommend the Tikitag/Touchatag reader, which
is re-branded ACR122U. Windows drivers are available either from
Touchatag site or directly from
ACR Producer. For Linux ACR122U is supported by
CCID 1.3.9 Driver. If Tikitag/Touchatag/ACR122U is detected by CPA appropriate
wrapper is used (the reader/driver is not PC/SC but CCID only).
As for popular Omnikey 5321 reader there seems to be some issue
with both Windows and Linux drivers. In case of Windows the
Waver is detected at good distance but connection is lost in a
moment. In case of Linux the distance is not that good with default
installation. It turns out this is due the /etc/cmrfid.ini file,
we recommend to delete it (it doesn't matter the actual content
of the file, the problem is its presence itself, seems like
some driver initiation bug). When deleted the reading distance
is same like in Windows but connection is stable and not lost.
All the demos use (preselect for the simplicity sake)
the last reader available, i.e.
we recommend to have only one reader connected. In case
of the multi-reader (e.g. the Omnikey 5321)
the last one is used. Terminal/reader setup can be tested in
CPA for accessing smartcard
