# Smartcard clock speed override
# Setting override specified speed for smartcard.
# Don't add setting unless you're sure what you're doing.
# In 99% of the cases the reader selects the optimal speed.
# Adding this setting either slows your card down, or might destroy it.

# SMARTCARD CLOCK FREQUENCY : <device> <freq>
