Jiangxi enterprises always show the reason for re-signing: the signature is not recognized by the system. According to the relevant information, in the process of handling, the online signature was not recognized by the system, and it needs to be re-signed with neat handwriting. Jiangxi enterprises set up e-window mobile client, which is a mobile enterprise processing platform entrusted by Jiangxi Provincial Market Supervision Administration. The client provides services based on Jiangxi enterprise registration network service platform, and provides services such as business handling, progress inquiry, real-name authentication, electronic signature and so on for applicants.
