Diners Club Protect Buy®

Security via SMS

Thanks to Diners Club ProtectBuy® shopping online is now even more secure: before completing an online purchase, every online retailer who offers this additional security standard will ask you to enter a code. Diners Club will send you a new code every time for free via SMS. When you enter this SMS Code, you make sure that only you, the cardholder, can complete a transaction with your Diners Club card.

How Does ProtectBuy® Work?

Cardholders who have submitted their cell phone number to Diners Club can automatically use ProtectBuy® when shopping at participating online retailers:

  • Once you have entered your card data while making a purchase, a pop-up window opens and asks you to enter a code.
  • You will automatically receive your one-time code via SMS within seconds. Furthermore, the SMS also includes a time stamp for the transaction.
  • Once you have entered the code, you can complete your transaction.
