Fingerprint opening system for guesthouse and fingerprint door lock thereof

The invention discloses a fingerprint opening system for guesthouses and a fingerprint door lock thereof. The fingerprint opening system comprises a front management system, the fingerprint door lock and embedded type software, wherein the front management system is used for extracting a client fingerprint and authorizing an authority and the time to the client. After the client is authorized with the authority for opening a corresponding room, the information is written into an IC card or a radio-frequency card through a card writer and finally transmitted onto the fingerprint door lock of a specific room through the IC card or the radio-frequency card so that afterwards, the client can directly use the fingerprint for opening when going in and out of the room. The fingerprint door lock identifies the fingerprint of the client and receives a command sent by the embedded type software to perform corresponding door opening or closing actions, wherein the embedded software has the main functions of comparing the fingerprint of the client, verifies the authority, sends out a door opening and closing command according to the authority and performs corresponding reactions to keystrokes on the fingerprint door lock. The fingerprint opening system is an integrated application of a fingerprint identifying technology and an RFID radio-frequency technology to the industries of hotels and the guesthouses. Through the application of the fingerprint identifying technology, the inconvenience of carrying room cards of travelers is reduced, and the safety of the travelers is improved.
