In the Bistro, take the test and become the chef. Then go to the bigwig spy and he will ask you to refill his wine glass. It has his fingerprint on it. Instead of refilling it, climb up into the kitchen vent, and cross the room by using the hanging lights. You will use the fingerprint on a security door at the B.A.D. Satellite Control Center.
you have to go into the BAD bistro and if you are wearing a Chameleon Suit you have to take it off then you go into the kitchen and talk to the chef and he will give you a memory test that is really easy and then you are a chef then you have to talk to the guy sitting at table and he asks you to fill up his cup and his cup has his fingerprint on it hope that helped ;D
From the agent in the B.A.D. Bistro. Get the job there as a chef and then get his wine glass (with his fingerprint). Sneak out through the kitchen vent and across the light fixtures.
The glass is for the B.A.D Control Center when you need to break in there. It has a fingerprint-only code.
