Embodiment Construction

[0009] Attached below figure 1 The present invention will be further explained.

[0010] The fingerprint lock includes a single chip microcomputer, a card reader and a relay connected to the single chip microcomputer, an electric control lock connected to the relay, and a fingerprint recognizer connected to the single chip microcomputer. Before use, insert any of the SD card, TF card, and MS card into the card reader, then the unlocker puts the finger into the fingerprint reader for identification, and the single-chip microcomputer stores the identified fingerprint information in the memory card in. You can carry a memory card with fingerprint information in your daily life. When you need to unlock the lock in the future, insert the memory card into the card reader, and then use the fingerprint reader to identify the finger information. The microcontroller controls the fingerprint information stored in the memory card. Compare, if they are consistent, the control relay will be ...

Abstract

The invention relates to a fingerprint lock. The fingerprint lock comprises a single chip microcomputer, a card reader and a relay connected with the single chip microcomputer, an electrically-controlled lock connected with the relay, and a fingerprint recognizer connected with the single chip microcomputer. Before use, any kind of memory card such as an SD card, a TF card, and an MS card is inserted into the card reader; then an unlocking person put a finger into the fingerprint recognizer for recognization; the single chip microcomputer stores the recognized fingerprint information into the memory card. The memory card stored with the fingerprint information can be carried about in daily life; when unlocking is needed some days later, the memory card is inserted into the card reader firstly; then the fingerprint information is recognized by the fingerprint recognizer; the single chip microcomputer controls the comparison with the fingerprint information stored in the memory card; if consistency is realized, the relay is controlled to pull in so as to unlocking the electrically-controlled lock. The memory card stored with the fingerprint information can be carried about, which puts an end to the risk of information stealing, and improves the safety.

Description

Technical field [0001] The invention relates to a lock, in particular to a fingerprint lock. Background technique [0002] The existing fingerprint locks basically have a storage chip for storing fingerprint data, and the fingerprint information of the unlocker must be identified before use, and the identified fingerprint information must be stored in the storage chip. When unlocking, if the fingerprint information of the unlocker identified by the fingerprint identification device is consistent with the fingerprint information in the storage chip, the unlocking is controlled. However, the built-in storage chip of the fingerprint lock will become a security risk. Hackers can extract the fingerprint data in the storage chip, thereby causing a security risk. Summary of the invention [0003] In order to overcome the shortcomings of the above technologies, the present invention provides a fingerprint lock with a storage chip that can be carried off the machine. [0004] The technical...
