They don't need fancy AI and all that. At some point someone will realize that there is a discrepancy between who badged and who is actually there, that 3 people badged and only one crossed the door, or maybe an employee will be caught red handed by a security guard. It will be treated as a serious security incident. Slacking off may be tolerable if the slackers otherwise bring value to the company, handing out one's badge, potentially letting unauthorized people in is something else. It will result in people getting fired on the spot, maybe even lawsuits. Engineers doing that would be anything but clever. And the "epic battle" will most likely be hopelessly one-sided and the movie will be about a bunch of people struggling to find a new job. If you don't want to commute, just stay at home, make up all the excuses you want, but don't play shenanigans with badges. If you bring enough value for the company despite "slacking off", you will get a pass, but if you mess with security, you won't.
