In hospital diagnosis and treatment services, from registration, examination, treatment, surgery, nursing to discharge, a large number of documents such as prescriptions, examination forms, laboratory tests, nursing orders, medical orders, etc. are signed. The paper signing form relies entirely on medical staff to print and hand sign, resulting in high signing costs for hospitals every year.

The National Health Commission requires that the electronic medical record rating of all Grade III hospital EMR should be above Grade 4, and that of Grade II hospitals should be above Grade 3. Among the 39 evaluation items in the Administrative Measures for Graded Evaluation of Application Level of EMR System (Trial) and Evaluation Standards (Trial), 1/6 of the evaluation items are related to electronic seal.

The state encourages the development of "Internet plus medicine", and major medical institutions actively explore the "Internet medicine" service model. The introduction of legally valid electronic seal to achieve real-Name authentication of doctors and online consultation and prescription has become a key link in the transformation. At the same time, the prescription of electronic seal can promote patients to fill medicine nearby and improve the efficiency of medical treatment.

The inpatient business of large hospitals has an annual discharge of 30000 to 50000 patients. From inpatient registration, diagnosis and treatment records to the signing of discharge medical records, there is not only a high demand for medical and nursing signatures, but also for printing and archiving the medical records of each patient. These paper archives are not only easy to stack and manage, but also difficult to share information.
