The Royal Bank of Canada revoked PIN rights for all of it employees at its brokerage firm who deal directly with clients Wednesday. PIN messaging or Personal Identification Number messaging allows BlackBerry users to send messages directly to other BlackBerry users, bypassing the BlackBerry Server. This poses security issues because of the lack of auditing on these messages. If a user were to delete a PIN message before syncing back to a BlackBerry Server, the message could be lost forever. This could violate many regulatory requirements overseeing electronic communications.
