I've used TAG on many an occasion and have always had good to great reactions. There's a review somewhere and it may be worthwhile taking a look at this and also at the video on JBTV.
There's also potential scope, once you know the secret for some adaptation.

It's not really an optical illusion - it just looks like one!
I use hot leads from time to time and it's funny how fire really excites people.
I could have done, what I would call, a cracking closer and then use hot leads to hand over my card and they seem more impressed with that and then go on about it..lol
The general public are a bunch of pyros
How about "Power Lunch" available on Penguin Magic......a toothpick penetrates a business card.......sort of card through dollar bill type of situation?
I dont perform Business Card Magic because I don't have a business card.
But from what I have seen, I quite like Oz Pearlman's "21st Century Phantom", which is included in his lecture notes "Into the Abyss".
Basically is a close-up version of Annemann's "Phantom Artist" in which a piece of paper (or business card in this case) is cut into widly, and is then revealed to have the face of the selected celebrity, heres a picture of the final result.
Name of someone you have never met before + Twin Peaks + business card = Priceless + optional Stigmata = They will never loose your business card but might be afraid to call you .
All I can really think of with business cards is what has already been mentioned, a version of Stigmata, and using the Twin Peaks move any which way you want to do whatever your heart desires.
