On Monday I was at the doctors offices. When I was in the waiting room, I was reading a book. A woman right next to me, who was so close I could place my hand on her made a phone call. When she was on the phone, she gave out her credit card number, expiration date, the three digit security number, her name (first name common) and spelled out her last name. And she also told about her account number to have paid. After she gotten done with the phone call, I talked to her. I told her I was not copying, or recalling the information she gave out. I told her it is not wise to say that information in a public place. As I told her: with a number of cell phones, someone can use the video of the cell phone, and most video also has audio. The video could be videoing their leg, but, the audio is picking up the information about your credit card. She was stun for around a minute, and she told me she never thought of that. Just saying, if you are in a public area, do not give out your credit card information.
