A permission control system includes: fingerprint modules, each of the fingerprint modules includes: a fingerprint acquisition unit configured to acquire a fingerprint of a finger; and a processing unit configured to determine whether the fingerprint that is acquired is in consistence with default fingerprints; and the system further includes: a control module configured to enable a corresponding operation permission according to a number of fingerprint or fingerprints in consistence with the default fingerprints. The system can flexibly enable a plurality of different operation permissions and hence can improve the flexibility and the convenience of permission control.
