Make the customer add the address to the account he will if
he's on the up and up with you.

A customer with a good card can dispute a shipment also
if the merchandise goes to another address then listed on his or her's account
I've found ... the police won't spend the time to mess with
a few hundred bucks. the card company leaves it up to you
to make sure the merchandise goes to the right place .

more on Credit Card Fraud  	
      
	  Actual theft of cards is only one form of credit card fraud among many, including:
Thieves who pick discarded receipts or carbons out of trash cans to get the card numbers; 
Dishonest clerks who make extra imprints of cards or scans them for personal use or to sell; 
Calls (or letters asking you to call) announcing that you have won (or been selected in a "marketing program" for) a free or unbelievably low-priced travel package. But, your credit card number is required for "identification purposes only." 
Protecting Yourself Against Card Fraud
DO:
     1. Sign new cards as soon as they arriveand call from home to activate them.

     2. Carry your cards separately from your wallet.  Keep a record of your
        card numbers, their expiration dates, and the phone number and address
        of each issuing company in a secure place. (Make copy of cards front 
        and back using a photo copier).

     3. Keep your card in view after you give it to a clerk.  Get it back
        promptly after they have imprinted or scanned it.

     4. Avoid signing a blank receipt.  Draw a line through blank spaces above
        total when you sign.

     5. Destroy all carbons and voided (when a mistake was made) receipts.  If 
        a clerk has to keep a voided receipt for the store's accounting 
        system, be sure to get a copy.

     6. Save all credit card receipts, open your monthly bills promptly and
        check your receipts and payments against the statement.

     7. Immediately report verbally and in writing any questionable charges 
        to the card issuer (some have a form on the statement for this purpose).

     8. Notify card companies in advance of a change in address.

DON'T:
     1. Lend credit cards to anyone.

     2. Leave cards, receipts or carbons where anyone can pick them up.

     3. Put a card number on a postcard or on the outside of an envelope.

     4. Give your card number over the phone unless you are dealing with a 
        company you are sure is legitimate and you initiated the call.


If Your Cards Are Lost or Stolen:
     Call the issuers immediately.  Most have a 24-hour toll-free number for 
reporting missing cards.  By law, you are not responsible for any unauthorized
charges from the time you report the loss or theft, so note when youreport 
the theft. The maximum amount you can be held accountable for, if the cards 
are used before you report their loss, is $50 per card.

What To Do About Suspected Fraud:
     If you think someone has illegally used your credit card, call the card 
issuer immediately.  It's a good idea to follow up your phone call with a 
letter.  Keep a copy for your records.
