Are augmented reality cards necessary/worth it?

[TwistedOrange]

I'm buying a used 3DS - and I'm wondering: are the AR cards necessary and/or useful at all? Because the one I am looking at buying does not have them.

you can print them out yourself

They're kind of cool, but yeah, you can print them out.

There are also some apps on Android that lets you just use your phone in place of the cards. Pretty handy.
