If you specialize in petrochemical litigation, use exhibits and some charts and pictures in the background to take a picture that looks like a petrochemical deposition. You can get it so cluttered that your client will have a hard time even finding your name. A business card should be clean, simple and elegant in its design. If you have too many, though, consider cutting back. CSR is probably the only one an attorney will recognize, anyway.
Business cards are cheap.
Consider having two sets made up. For attorneys, a simple card describing a few of the services you provide. If you have a specialty, work it in. The attorney couldn't care less what CAT system you use, and has probably never heard of it, anyway. For other reporters from whom you are soliciting referral business, focus the other direction.
