Summary of the invention
Technical problem to be solved in the utility model overcomes deficiency of the prior art and provides a kind of and can independently finish fingerprint collecting, compares, sends the confirmation a series of activities, has the fingerprint usb key of protector for sensor.
The technical scheme in the invention for solving the above technical problem is: this fingerprint usb key; comprise upper shell; lower house; protecgulum; circuit board; USB interface; upper shell and lower house are connected to form housing; be provided with circuit board in the housing; housing one end is provided with USB interface; USB interface is outside equipped with protecgulum; protecgulum and housing socket; its design feature is: have the transducer frame on the described upper shell; be provided with the fingerprint collecting transducer with transducer frame relevant position on the circuit board; also be provided with process chip on the circuit board, this process chip and fingerprint collecting transducer; USB interface connects respectively, and described housing is outside equipped with over cap.
Over cap described in the utility model and housing are for being rotationally connected.
Over cap described in the utility model and housing are for being slidingly connected.
The utility model compared with prior art has the following advantages: 1, be built-in with process chip, can break away from other-end equipment and independently carry out calculation process, and comparison by after send and confirm instruction, convenient, fast during use; 2, because process chip is built-in, need on terminal equipment, additionally hardware be installed, reduce hardware cost and comprehensive use cost; 3, housing is outside equipped with the over cap that rotates or slide, and when not in use, can protect the fingerprint collecting transducer, and volume is small and exquisite, and is easy to use.
