+Voltage selection
+=================
+
+You can change the voltage level using the Info.plist configuration file.  The
+Info.plist is installed, by default, in
+/usr/local/pcsc/drivers/ifd-ccid.bundle/Contents/Info.plist
+
+The voltage level is set in the ifdDriverOptions field. It is a binary OR
+combinaison of 4 different levels.
+
+-  0: power on the card at 5V (default value)
+- 16: power on the card at 3V and then, if 3V fails then use 5V
+- 32: power on the card at 1.8V, then 3V and then 5V
+- 48: let the reader decide
+
+By default the voltage level is set to 0  and correspond to 5V.
+
+You have to restart the driver so it read the configuration file again
+and use the new debug level value.  To restart the driver you just need
+to unplug all your CCID readers so the the driver is unloaded and then
+replug your readers.  You can also restart pcscd.
