Thanks for reaching out to Discover. Unfortunately, we don't share the number of Discover cardmembers who have contactless cards.
Discover uses RF-enabled technology and we believe these contactless payments are secure. Unlike RFID, which can operate at ranges up to 25 feet, contactless payment devices are designed with RF-enabled technology that operates at very short ranges – less than 2-4 inches – so that the consumer needs to make a deliberate effort to initiate the payment transaction. For contactless payments, Discover uses added security technology both on the contactless device as well as in the processing network and system to prevent fraud, and with Discover's 0% fraud liability, Discover cardholders have the added protection of never being held liable for any fraudulent activity on their cards.
Importantly, the Discover Zip contactless card has a unique security feature in that the verification value changes each time you use it -- so that any skimmed data could not be reused.
