Our country's law does not stipulate that IOUs must be printed by fingerprints. An IOU is valid as long as it truly reflects the facts of the loan and does not violate the law. If there is a signature on the IOU and a payment voucher, it can prove that there is a real loan relationship between the two parties, and the real and legal loan relationship is protected by law, and the debtor should bear the responsibility for repayment.
According to Article 90 of the General Principles of Civil Law:
Legal lending relationships are protected by law.
Article 89 In accordance with the provisions of the law or the agreement of the parties, the performance of debts may be guaranteed in the following ways:

2. The debtor or a third party may provide certain property as collateral. When the debtor fails to perform the debt, the creditor has the right to discount the collateral or give priority to compensation with the price of selling the collateral according to law.
