Im presently writing a story in which one of the characters wishes to safeguard a precious heirloom inside a bank vault. Depending on the bank, what would the procedure be? Let's say the person already has an account. If the person wishes to retrieve her property once deposited, would she need to show an ID or would her physical presence be enough to gain access to the item stored? What is the procedure some banks use? Any help would be awesome. THANKS.
