There are many people who should have a business card but don’t. Who you might ask? Those who should have a business card but many not include job seekers, those who work from home, and of course small business owners. Job seekers should have a business card to hand to potential contacts, those who work from home (even those who sell Avon) should have business cards that offer their service or product, and small business owners should always have a business card to use to promote their business.
