You think too much. At least this kind of online fraud has not been found so far. Internet fraud is a kind of remote non-contact fraud. The method you mentioned is common in contract fraud that must be carried out face to face.

Besides, even if there is such fraud, do you mean the victim who was impersonated? Or the person who was cheated? If it is the former, there is no need to take preventive measures. This is completely exempt from liability in judicial practice. No matter what crimes others commit by pretending to be your signature or ID card, you will not have any legal or civil liability. If you mean the latter, you need to transfer some wealth in business, general loans or other social relations. If you don't know the identity of the other party at all, don't trust the other party rashly with only one ID card, because fake ID cards can be made everywhere. If you really need to verify the authenticity of your identity, you must check the authenticity of your identity information with the public security organ where your household registration is located. If the other party escapes or shirks, it means that there is a ghost in his heart.
