A service in which doctors sign medical reports or prescriptions to confirm their accuracy. Generally speaking, when a doctor issues a report or prescription, he will sign his name and fingerprint on the report or prescription as a guarantee to confirm the accuracy of the report or prescription. The words or patterns used for this purpose are usually the exclusive signatures of doctors, because this is a way for them to mark them to confirm that they are the doctors who issued this report or prescription. Handprint refers to the doctor's signature on the medical report to confirm the accuracy of the report.
