When it comes the issue of money transportation to and from the bank at exchange time, any thinking person would already have their currency in a safe deposit box, so when the time comes, you transport your currency a matter of feet, within the confines of the bank, with armed guards standing by. Or better yet, and far more intelligent, have your currency in a depository. Then you hold an SKR ( Safe Keeping Receipt) which you present to the depository and THEY transport your currency to the bank. [Note: Consult your financial advisors to learn the pros and risks of holding currency in a bank’s safe deposit box or with a depository.]
