When using Doors rather than Turn-Stiles, it is possible for one person to authorise the opening of the door and for
several people to walk through that door. This will make it difficult (if not impossible) to implement this type of
solution.
If a User A hands a key over to User B without returning the key to the Traka Key Control system first (which is what
they should do), the key status will not be cleared from User A and so User A will not be able to leave the site. On the
downside, User B will be able to leave site (provided they have no keys booked out to them) with the keys that were
handed to them. If this does happen, User A will not be able to leave and so users will quickly learn that they must
always return keys to the Traka Key Control system.
