Proper card acceptance
1. Check the card security features (listed below). Make sure that the card has not  
    been altered.
2. Swipe the stripe. Swipe the card through the terminal in one direction only to
    obtain authorization.
3. Check the authorization response. Take appropriate action for the specific
    response:
 
 
4. Match the numbers. Check the embossed number on the card against the four digits
    of the account number displayed on the terminal.
5. Request a signature. Have the cardholder sign the transaction receipt.
6. Check the signature. Be sure that the signature on the card matches the one on
    the transaction receipt.
 
If you suspect fraud, immediately make a Code 10 call to your acquiring bank's authorization center.

Dealing with unsigned cards
  
If the signature panel is left blank...

 
 
If the card has a “See ID” in place of a signature…
 
If the signatures appear reasonably the same and the authorization request is approved, go ahead and complete the transaction.
Six warning signs of fraud
Certain customer behavior could point to card fraud, but it doesn't necessarily indicate criminal activity. You know your customers, so let your instincts steer you in the right direction. 
 
Watch out for customers who:
1. Purchase a large amount of merchandise without regard to size, style, color, or
    price.
2. Ask no questions on major purchases.
3. Try to distract or rush you during the sale.
4. Make purchases and leave the store, but then return to make more purchases.
5. Make large purchases just after the store’s opening, or as the store is closing.
6. Refuse free delivery for large items.
