This system has many security flaws like; the seller person can steal or clone the card and card information without the owner's knowledge.

Recently with the invention of CHIP & PIN technology it becomes harder for fraudsters to use a stolen card, because if someone gets the card they might not be able to make fraud transaction without knowing the PIN.
