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.
