Legal analysis: the name on the loan is misspelled, but it is valid if you press the fingerprint. The borrower's name is wrong if it is a handprint. There are generally two situations. If it is a forced loan, it is invalid. If the debtor wants to evade the debt and deliberately miswrites his name, the IOU is valid.
