On the arrival, cleared to cross twinz at 11000 ft, approach checked our assigned altitude. We were at 11000 ft. ATC asked us to change xponders. The altimeter was set improperly at 30.67 instead of 30.07 (wrong altimeter setting). Continued with corrected setting, ATC didn't say that there was any problem.
