You promote your small business when you hand out a business card; you're hoping that the person you're giving it to will use the information on the card to contact you.
I used one of my photos from the Buddhist temple as I wanted to us one of my photos from the temple that is interesting but not something that will show too much so that the person is interested and will look at my website. I don't have my phone number on the card as I don't want it to be called from anyone for no reason if a person wants to contact me they can email me which is on the business card.
