That would be a terrible user experience. Most places are not diligent about ensuring each employee separately badges past a barrier. Common to hold the door for Bob while he is juggling a coffee. Boom, missed badge swipe and now things are forever imbalanced.
Notably Apple expects each person to badge in. Google does not, and it is pretty easy to follow a group of people in to a building, but you cannot do that at Apple.
Because nobody has ever jumped over one of those or triggered the motion sensor on the other side of those paddle gates or gone around the side or underneath...
