Secure NFC PTY. LTD. has filed its first lawsuit, accusing Mastercard (3:23-cv-00853) in a new Eastern District of Virginia complaint of infringing a single patent payment patent through the provision of its Masterpass digital payment service. At issue is the service’s Tap on Phone feature, as used to accept payments on an NFC-enabled device from a contactless card or mobile wallet, including functionality that replaces payment card account numbers with unique 16-digit tokens, and the use of “dynamic data (cryptograms) generated using EMV-based cryptography to secure the transaction” (as described on the Masterpass website).
