Coded lock based on NFC recognition function

The utility model relates to a coded lock based on an NFC recognition function. The coded lock is characterized by comprising an NFC induction module, a password input module, a power module, a first lock cylinder connected with the NFC induction module and a second lock cylinder connected with a microprocessor module. A dynamic password input module is an input method switchable intelligent liquid crystal touch screen, a dynamic password of the dynamic password input module is set to be a string of numbers or letters or the mixture of the numbers or the letters which are 6 to 10 digits. Compared with the prior art, the identity recognition coded lock based on NFC is provided, and personal identity information recognition is facilitated; only when the dynamic password on a mobile terminal APP input by a user is consistent with information stored on the coded lock can the coded lock be unlocked, and the safety of the coded lock is further improved.
