Hello, guys

About 2 months ago I purchased this "Fingerprint Recognition Module for Arduino Optical Fingerprint Sensor" from banggood.com:
http://www.banggood.com/Fingerprint-Recognition-Module-For-Arduino-Optical-fingerprint-sensor-p-1104739.html?rmmds=myorder

It arrived yesterday and imagine my surprise when the module actually had 7 pins instead of 6, and was way smaller than they should be (the space between two pins is like 0.8 - 1 mm). Here is what it looks like (I am sorry in advance for the bad quality of the pictures):

So how do I connect it to Arduino UNO?
