The system and number of this bank are not quite the same as those we usually use. It belongs to another system. The specific subordinate units are also different, depending on which bank the prison cooperates with. But the use method is the same as ordinary bank cards, and their family and friends can use this bank card to transfer money. Users' family and friends will receive a notice from the prison asking how to remit money to users. Users can find their own bank and then handle it.

Is there a refund for the money deposited by the detention center for prisoners?

Can be returned. The account that the detention center deposits money for prisoners is the suspect's own account, which belongs to personal account. The money in it belongs to the personal property of the suspect. If it is not used up, it needs to be returned. This is an obligation that the detention center needs to fulfill. If the money in the card is not used up after the suspect comes out, he can go through the relevant formalities to refund the money.
