2/ I would use entry-exit (or simply entry) permit for visitors. 'Permit' can be used for employees too, but more often people say, "show me your ID card." Sometimes, I have heard of the usage of 'pass' also.  According to my dictionary, 'pass' is an official piece of paper which shows that you are allowed to enter a building or travel on something without paying. However, 'exit pass' for visitors is not precise since one must first enter before one exits.

Please help me find the most commonly used words for the phrase in bold type: 1/ A worker in a factory is not allowed to take anything out of the factory unless he has a written permission of his manager and he has to give this paper to the security guard before taking things out of the factory. What words must I use to describe this   written permission  .( eg.taking-out form ....) > The worker has to show the  taking-out form  to the securuty guard  pass  /   exit pass I think the taking-out form  here is not correct . So please correct for me. 2/ A passenger who wants to board a plane must show a boarding pass . So , can I say a visitor who wants to enter the  factory must show an entry pass to the  security guard and a visitor who wants to exit the factory must show an exit pass? Please help me find the most commonly used words for an entry pass  and exit pass ( I think entry pass and exit pass are not correct here )  Both would be acceptable in the UK. I would appreciate it very much if you correct my sentences
