Data concentration system and integrated teller system have been the trend for bank transaction system. However, what is widely used in banks now are still traditional  “card + password”, signature, director authorization, which do not meet the high-security demand for bank transaction system. The existing “Card + password” identity authentication has some  flaws:: 

Firstly, because of weak risk awareness or nervous emotion of bank tellers, there is a serious card mixture among tellers, which results in the leak or loss of password and makes the whole system in big security trouble—not only brings economic loss to bank but also damages the bank’s social image. 

Secondly, because of its technical deficiency, “Card + password” identity authentication is worse in security, easy to copy and pattern. 

Finally, The shortcoming of the traditional method that only objects but humans can be recognized cut the connection between authorization and user, increasing the difficulty for management. 
In recent years, cases such as password stealing, visiting system beyond his authority by disguising ID, illegal money filch are emerging. So how to enhance security control of inner personnel, how to eliminate security trouble of transaction system and to reduce the financial crime of inner personnel, become the urgent problems to solve.
