First there is what is called “mail non-receipt fraud” which is when a new or replacement card is sent by the bank and never received by the person it was supposed to go to. This has been mostly combated by the banks sending out inactive credit cards where the person has to make a phone call in order to activate the card. Otherwise it can’t be used. Unfortunately there are some banks that do not do this and still send out cards that are already activated. Then there is what is called “chargeback fraud” where a legitimate cardholder uses the card to purchase goods or services. Then when the statement comes they call the credit card company and claim they never received the item or service or that they never authorized the transaction.

Another type of credit card fraud is called “skimming” where an employee or merchant makes a second copy of the person’s credit card details before processing the payment. This copy is then sold on the black market to professionals who clone illegal copies of these cards. Fortunately, skimming has become less of a problem since the introduction of CVV and CVS codes. These are not encoded on the card strip but are physically written on the back of the card. This is a required three digit code to finalize all transactions. Without this code even a cloned credit card will not work. Skimming at ATMs has also been a problem. What the illegally set up ATM machine does is place a skimmer device somewhere in the machine that reads the magnetic strip attached to the card. This is used together with various devices that monitor the keypad of the ATM by attaching a fake fascia over the original keypad. Fortunately, this is not as common today as it was years ago when ATM machines were relatively new.
