Problems solved by technology

However, there are also problems such as the fact that the signer opens the USB-KEY through password verification, which is difficult to avoid signing on his behalf, and the reliability is insufficient; when the holder does not bring the USB-KEY with the electronic signature, he needs to get the USB-KEY. The time response is poor when the signature is completed; when the personnel changes abnormally or the USB-KEY is damaged or lost, it is difficult to freeze or suspend the use of the electronic seal in time, and the management and use are not flexible enough
