Well, here is the routine sequence:
1) you ask for the spectator ID card and place it yourself
in an envelop, and leave it on the table
2) you place your ID card in an envelop
3) you ask
the spectator to devine what is written on your ID (!!!!)
4) he divine nothing (wow!!!)
5)
you devine what is on his ID card
Real mentalism is about what people think, feel, are...
not what is written on a paper. You should pretend to have a sort of "connection", and for that, you
need a "mind" to be connected with.
So, to be able to present this effect based on the
usage of an ID card, you should have a perfect excuse to ask the spectator ID card and place it in
an envelop, and then, forget about it for the rest of the routine!!!
There is absolutely no
justification for this part in this routine!
And the part where you ask the spectator to
guess your ID information and fail is sooooooo bad! If you do that, you should be able to make him
guess correctly at least one little thing, otherwise you make him feel like a sucker.
