Scan your finger… discover your mood!
This one (called it crap and old, yeah!) that I really enjoy is an application available for your iPhone/iPod/Ipad.
Simply put your finger on the scanner, then watch. It scans and verifies your fingerprint. It can actually validate your mood and emotion of the very moment. In Love? Relaxed? Sad? This will tell you so!
I don’t know how it works, but fun isn’t it?
