At the end of the clerk’s shift, a supervisor unlocks the register and retrieves the internal tape. The cash drawer is removed and replaced with a new cash drawer containing a known amount of start-up cash (float) for the next clerk. The supervisor and the clerk whose shift has ended take the cash drawer to the cash room (treasury), where the contents are reconciled against the internal tape. The cash drawer should contain cash and credit card vouchers equal to the amount recorded on the tape.
