Patent attributes
A dynamic transaction card may be paired with a user application executed on a user device card to facilitate multi-factor authentication of a user by utilizing the dynamic transaction card as a physical token. Various communication technologies may be utilized to create a connection between the dynamic transaction card and the user device application which may include wireless connections and physical connections. Validation information stored in a passive tag on the dynamic transaction card may be received by the user device application, which may evaluate the connection between the dynamic transaction card and the user device, log in credentials of the user, and user information stored in a digital security delivery storage to authenticate the user. This unique pairing of the dynamic transaction card and user device application may automatically facilitate a secure multi-factor authentication by utilizing the dynamic transaction card as a physical token.
