Fingerprint registration method and device and terminal thereof

A fingerprint registration device comprising:

• a processor;
• and
• a memory connected with the processor, the memory comprising a plurality of program instructions executable by the processor, the plurality of program instructions comprising:
• a retrieve module, configured to cause the processor to retrieve feature information of a fingerprint recorded every time based on preset index types when the fingerprint is registered;
• a matching module, configured to cause the processor to match the feature information based on preset index information corresponding to the index types to determine whether the fingerprint recorded every time is effective;
• and
• a processing module, configured to cause the processor to signal a successful fingerprint registration if it is monitored that a number of effective fingerprints recorded reaches a preset number of fingerprint templates.

A terminal device comprising a casing, a processor, a memory, a circuit board, and a power circuit, wherein the circuit board is disposed in a space surrounded by the casing;

• the processor and the memory are disposed on the circuit board;
• the power circuit is configured to supply power to various circuits or components of the terminal device;
• the memory is configured to store executable program instructions;
• the processor runs a program corresponding to the executable program instructions through reading the executable program instructions stored in the memory to perform following operations:
• retrieving feature information of a fingerprint recoded every time based on preset index types when registering the fingerprint;
• matching the feature information based on preset index information corresponding to the index types to determine whether the fingerprint recorded every time is effective;
• and
• signaling a successful fingerprint registration if a number of effective fingerprints recorded is monitored to reach a preset number of fingerprint templates.
