Call the police. In case the other party extorts money in the future, you can ask the police to open a certificate to prove that you have not received the corresponding money, but don't expect to catch the liar. After all, the loss did not happen. Or when the other party uses your signature and fingerprint to engage in other fraudulent activities, you can also ask the police to prove it to you. The police have all the records of calling the police.

If you don't feel at ease, just break a little money and make a small statement in your local evening paper and Time Media, and it won't cost you a few dollars to declare that you were cheated into signing an invalid contract and lost an unmarked copy of your ID card.

When you need a copy of a similar ID card in the future, be sure to indicate the purpose on it.

I hope the above answers can help you.
