Zusammenfassung:The utility model relates to a multifunctional wireless fingerprint terminal which is mainly composed of a liquid crystal display (LCD), a fingerprint sensor, a microcontroller, a WiFi module, a loudspeaker and a matrix keyboard. The microcontroller writes data into the LCD via an SPI (Serial Peripheral Interface), controls the fingerprint sensor and the WiFi module via SCIs (Serial Communications Interface), and is connected with the loudspeaker and the matrix keyboard via IO (Input/output) ports. The terminal employs wireless communication, and has functions of work attendance, consumption and gate inhibition for campus.
