Ok i have idea for a routine, it involves magic but the trick takes less than 2 minutes to learn.
Right, you have five playing cards on the table and make out some story about what each one means (similar to tarot cards), link the stories to an earlier discussion if possible.
The trick is you make her pick the card you want (the trick takes some explaining, but is super easy, i'll post it if anyone's interested). the 5 cards are shuffled laid out in line on the table , before you run the trick say something like, "i bet you'll pick the 10 of diamonds because etc" make her pick that card (i'll explain how if people are interested).
tell her to keep it. a while later talk about the trick again, say you did it on yourself, open you're wallet to reveal the same card, and perhaps number close on this, similar the the ripping paper in half method, but write you number on your card hand her the pen and swap cards.
just an idea, let me know what you think
