Method and system for generating a dynamic card verification value for processing a transaction

Abstract

Systems, methods, transaction cards, mobile devices, processors, and computer memory programmed with machine-readable instructions, for providing a dynamic Card Verification Value (dCW) to a user of a transaction card. A mobile device associated with the user and with the transaction card initiates a non-payment near field communication (NFC) with the transaction card, receives a message from the transaction card in the non-payment NFC communication, transmits a prompt to an IP address or web address over a global computer information network, and receives a secure communication from containing the dCW from a server accessible from the IP address or web address in response to the prompt. The dCW code is then provided to the user. In embodiments, the non-payment NFC may be initiated via a card tap, a user interface, or a communication from a website.
