Fraud Prevention

Each year millions are lost due to fraudulent card activity. It is our intention to help you minimize your risk of fraud.

Below are some guidelines:

1. There should be a distinctive world map background on the front of the card
2. Check that the back of the card shows a Diners Club hologram
3. The card number must be repeated on the signature panel on the back of the card
4. A three digit C.V.V number should appear on the signature panel on the back of the card
5. Check that the card number on the face of the card matches the last four card numbers on the back of the card

1. Check the expiry date, the condition of the embossed characters (no smudging etc) and that the Card number, CVV number and our logo are clearly printed on the white strip
2. Never hand over goods purchased with a Diners Club Personal Card to a customer who cannot produce the Card;
3. Request ID and check that the date of birth matches the estimated age of the Cardholder;
4. Check that the number on the Card is the same as that on the slip;
5. If the member disputes the charge, Diners Club will request the signed billing form or Credit Card Charge Form (CCCF) for proof of transaction. However, typed or handwritten Card details are not proof that the Card was used. Ideally, you should make and file an imprint of the member's Card after each transaction to prove that the Card was present at the time of the transaction.

Should there be any doubt please call the Diners Club call centre on 0861 DINERS
