Discover Online Fraud Solutions: The Power of the Layered Approach

To help protect Discover® Card transactions from online fraud, Discover offers three easy-to-deploy solutions designed to be used in a layered approach—spanning from pre-authorization to post-fulfillment. Let’s take a deeper look at each of these three powerful solutions.

Protect Debit Transactions with Internet PIN Debit

Internet PIN Debit reduces chargebacks and fraud through online PIN entry and scrambling using PaySecure® technology from Acculynk. When cardholders enter their debit PIN to pay for purchases online, a graphical PIN pad appears. The numbers re-scramble each time a new digit is entered and no PIN information is ever stored.

Mobile security

An additional layer of protection for mobile transactions

Discover® Tokenization sends sensitive PAN data to a more secure location where it is authorized by issuers and acquirers. It is then replaced with a unique token number for each transaction, making it meaningless to anyone unauthorized to access it.
