hi asked:


When we type in our credit card numbers to buy something from an online shop, can the online shop staff see our credit card numbers and 3 digit code and use it again and again to take our money? Also, I just bought something from an online shop, and somehow the shipping fees were not deducted and now they ask me to FAX or CALL in with my credit card number. Isn’t that unsafe? What can I do?
