Every Adafruit_Fingerprint.h library example has this simple test at the beginning. What do you see when you add this to your code?
finger.begin(57600);
if (finger.verifyPassword()) {
Serial.println("Found fingerprint sensor!");
} else {
Serial.println("Did not find fingerprint sensor :(");
while (1);
}
You are using software serial, and I would take the baud rate down to 9600, and bring it up when things are working. Higher baud rates can be less reliable.

The device is like a secured buggy bank it will unlock in 5 seconds then lock again. The Lcd must display if I'll insert the coin it must show "Total : "
after that if I tried to enter my finger it will active the Lcdclear then displays "Welcome Raven" and unlock the solenoid lock for 5 seconds then goes lock again
