Fingerprint Sensor Help!!???

Hi! I just bought a second hand arduino kit in our local area. I wanted to try it; however, I am having a problem identifying which of the pins is VCC/Gnd since there is no marks. Also, I am having a problem looking for a datasheet for it. Here is a link of the fingerprint sensor I am currently using:

The IC being used is BRMicro BR6211. I tried to search for a module; however; I could not find an english datasheet for it. I hope someone could help. Thanks!
