From the point of view of evidence, the scanned document is a picture, which exists in the form of a copy and can be tampered with technically. Therefore, the proof function of the scanned document itself is very low. Unless the other party approves the scanned document, it is necessary to provide other relevant evidence to support it, forming a chain of evidence. The scanned document can be used as the final evidence and has high probative effect. A scanned copy is equivalent to a photocopy, and it is difficult to get court support by going to court alone. The original may also be tampered with, but it can be authenticated. If the original is true, it can be used as evidence to identify the facts, while the scanned copy can not be directly identified as evidence even if it is true. This is the difference between the two.
