As long as you sign the interrogation record of the police station, it can take effect without fingerprints. According to the law, after making a transcript, the public security organ should ask the person being questioned to check the contents of the transcript and sign on each page. However, in judicial practice, the public security organ will ask the interviewee to press his fingerprint while signing. But the purpose of fingerprinting is to further confirm that the transcript was personally confirmed by the interviewee. If the person being interrogated only signs the interrogation record and does not press the fingerprint, it will not affect the legal effect of the interrogation record itself.

Under normal circumstances, the content of the confirmation record of the police station requires both personal fingerprints and personal signatures. But sometimes the implementation is not particularly strict. Standing on the legal level, it is similar to signing a contract with us. Whether we have our own handprints or not, as long as we sign our own names, the contract will have legal effect. Therefore, we need to take every word we say at the police station seriously to ensure that it is true and effective.
