A few months back I was looking for a hotel accommodation and finally ended up in a moderate one. I handed over my card to the person who was sitting at the reception. But then he said the swiping machine was inside and he had to take may card there. I felt something not right and insisted ongoing with him. They also placed a copying machine alongside. I wonder why they kept the swiping machine inside while it has to be used in front of the customer. They can easily take a copy of our card and use it later. If they know the card number, CVV and expiry date they can easily use it in our absence from anywhere in the world. Then onwards I always keep the CVV covered with a thin black colored plastic on it. Do you have any bad experience with your card transaction like this?
