When combined, 财务章 (cáiwù zhāng) literally translates to “wealth-affairs stamp,” a very direct and accurate description of its function as the seal for managing a company's financial matters.
The importance of the 财务章 is rooted in China's long history of using official seals to signify authority, dating back to imperial times. While a signature represents the will of an individual, a seal represents the official, legally-binding will of an entity—be it an emperor or a modern corporation.
The 财务章 is used in virtually all official financial activities. Its use is not optional; it is required by banks and government agencies.
