Never Offer Your Business Card With One Hand
Source: https://www.thebalancesmb.com
If you happen to be meeting with someone for business, never offer your business card by using just one hand. It is important that you hold your card using both hands while you present it to the one you are giving it to, as this is seen as a sign or respect and proper business etiquette. And when you receive a card from someone, always make sure that you at least peek at the card when it is given before tucking it away somewhere safe.
