sensor.on("ready", function(){

	sensor.read()
	.ok(function(id){
		console.log("Fingerprint found! ID",id);
	})
	.fail(function () {
		console.log("Unknown fingerprint");
	})
	.wait(function(){
		console.log("Put fingerprint");
	});

});

##Serial Ports

var FingerPrint = require("zfm20"),
	sensor;


sensor = new FingerPrint();

sensor.ports(function(port){
	console.log(port); //check available port
});
