The AT88SC102 chip contact IC card has a fuse operation. Before and after the fuse is blown, the security features are different. Before the fuse is blown, the access of the entire card is controlled by the user's password and the read attribute control bits of each application area. After the fuse, the card's access is affected by the user's password. The application area reads and writes the attribute control bit and controls the erasure password of each partition.
