Yes, business cards can still be a great way to market your business.
if they are kept in a wallet or purse, or even distributed to friends as a referral, they are definitely worth their investment.
The question really is not whether to use them but what is your strategy? What will be printed on the cards, something that is compelling and different and stands out from the crowd.should you use them as a referral marketing tactic? In which case, should you have a commission structure for any referrals?
Business cards can be as simple or as technical as you’d like them to be, but they need to form the wider part of your business marketing strategy, rather than be a stand alone separate piece of branding.
I’ve waffled on a bit here, but I hope this helps. =D
