A、Say "Thank you." and put it away. B、Say "Thank you." and examine it briefly. C、Say "Thank you." and put it in your card file.

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. Please feel free to call me if you have any suggestions." If you wish to offer your card to a long-time associate, you can say, "Did I ever give you my card?" or "I mean to give you my card." 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 "I neglected to bring them with me." Giving someone your card, of course, does not obligate you to continue contact, nor does accepting someone else’s card. When you do receive a card, say "Thank you." and examine it briefly before putting it away. You can use a business card that you received to refresh your memory about someone’s name and title before your next meeting. You can also record notes about the meeting on the back of the card, or place it in your card file.
