The police can find all the details before the cancellation of the bank card. The transaction records and personal data of bank cards have been kept in the bank since the date of issuance. The public security organ has the right to inquire about the account information of other people's bank cards held and used by criminals. As long as the case handlers produce relevant survey data to prove, the bank will cooperate with the public security inspection law to inquire about the details of the bank card. If it is a cancelled bank card, generally speaking, only the bank details of the last two years can be found, and of course, some banks will keep it.
