as far as I know, the personal signature of Beijing enterprise service e-window refers to the personal signature on the document when using e-window to handle enterprise services. Generally speaking, the change of personal signature will not have a direct impact on personal daily life. However, if you need to use your personal signature to handle some important documents or contracts, such as banking and legal documents, you may need to go through the relevant procedures again to ensure legality and effectiveness. In addition, if you use your personal signature in the workplace, the change may involve the adjustment of related contracts, authorization documents and other business aspects. In short, the change of personal signature may have an impact on specific business, but it has little impact on daily life.
