“Finger vein authentication Key BOX” is a battery-powered key box which uses mofiria FVA-E2SX module and a low cost microcomputer. FVA-E2SX has a RS-232C interface other than USB interface, and it allows the low cost microcomputer to control the device.
The system consists of: 1) key pad to input ID of the user to be authenticated; 2) LED for indicating the status; 3) speaker for beep; 4) SD card to store the pre-enrolled template of the user; and 5) solenoid for door open/close.
The control operation is very simple as follows:
- Input ID of user to be authenticated.
- Load the corresponding template from the SD card using the ID, and import the template to FVA-E2SX.
- Detect the placement of a finger on the device, and send the authentication command to FVA-E2SX.
- After receiving the authentication result, microcomputer opens or closes the door.
