Good point that I completely missed.
The card is not just for the people that see you, it's for the people they pass it to.
"Hey Bob - I want an entertainer who can sing and dance...do you know any?"
"Yes John - I saw an entertainer called Danny something. He does magic too - I'll get you his card"
End.
No more.
Danny - you do not understand the basic reasons behind, or execution of promotion, (either cards or websites). Go and read some books and take some professional advice first. It will cost you, but this is called investing for your business. This is not a game, you need to take it seriously or not at all, and you are being serious about all the wrong areas, for all the wrong reasons.

For people to see what magic you do, I always suggest a prominent link to a youtube channel with some well shot performances (and a showreel)

Works better than the right wording on a business card
