Uh....
Where did you get this info from?
Source please

It would be simpler if it worked on facial recognition, as it does scan the face (which is how it got the face for SAO)

[quote=@LupusIntus]Moving down the bluff towards one of the creatures he noticed a floating red crystal above its head which he clicked for a small display of information: “Boar – Level 1”
‘boar hide’ and one ‘chunk of boar meat’ along with 100 ‘XP’ and 5 ‘Cor’,

Um...
You can't actually click the crystal, since ... you would have to be standing at the Frenzied Boar to do that
Also, the only information you can see, is the name of the enemy above the crystal
The color of the crystal will give an indication of the monster's level, based on your level (Red = same level, darker = higher level, lighter = lower level)

EXP and col I think will be moderated and monitored for levels and stuff. 
(Discussing the details with Caits)
(Don't worry, you don't need to remember what your exp is, and how much you need to level and all the calculations and stuff, it will be just rough work, so you don't just suddenly jump more than you should be and things like that
(We will just check things like, okay, you just reached level 3, but you only killed 6 lower leveled monsters and are trying to say you reached level 4, the exp from that monster should not be enough to get close for example)
