Business cards are less important in American culture than they are in Asian culture. But knowing the right way to handle business cards is a useful skill wherever you are. Requesting someone's business card is a straightforward process. You need only say:"Do you have a business card?" or "May I have your business card?" When you want to present your own card, you can say, “Here’s my card. Feel free to call me if you have any other questions." Or, you might say, “Please send the information to this address. I look forward to hearing from you soon." It's not polite to directly refuse a request from someone for your business card. Instead, you can say, "Sorry, but I'm afraid I'm all out at the moment." or "l forgot to bring them with me." When you do receive a card, say "Thank you" and examine it briefly before putting it away.
