Signing and fingerprinting on blank paper will have serious consequences, especially if it is used by criminals for deception, impersonation, forgery and other purposes, it will have legal and economic consequences and losses, such as fraudulently using power of attorney, forging IOUs or IOUs, and issuing certificates.

Take IOUs as an example:

At present, the most common way for private lending to issue IOUs is that lenders write IOUs and borrowers press their fingerprints. For the borrower, the loan issued in this way is extremely risky. According to the trading custom, the original IOU shall be kept by the lender. If you change the IOU after the lender, such as adding a few zeros to the loan amount or adding interest, it is difficult to distinguish it because it is the lender's handwriting. Once a lawsuit occurs, it will be very difficult for the borrower to prove that it has been altered by the lender.

The judge suggested

In order to avoid this risk, the following preventive measures can be taken:

1. Don't sign on white paper easily. If you really need a signature, be sure to indicate the purpose next to it.

2. The content of the IOU is written by the borrower himself, and it is difficult for the lender to tamper with the content of the IOU.

3. After the IOU is issued, the borrower keeps a copy and requires the lender to sign the copy for confirmation, which proves that the copy is consistent with the original, so that it can be used against the lender when giving evidence.
