US Patent 10984420 Transaction device

A transaction system performs a transaction for a purchase of goods or services. Information about a purchase of goods or services is displayed on a display of a transaction device. The transaction device receives from a user, primary identification data which comprises biometric data that identifies the user. The transaction device receives from the user, secondary identification data which identifies the user. The secondary identification data is in addition to the primary identification data, and the secondary identification is of a different type than the primary identification data. A primary biometric identification parameters database is accessed to verify identification of the user. A secondary identification parameters database is accessed to confirm identification of the user. The transaction device provides to the user a transaction failure message when either the access to the primary biometric identification parameters database fails to verify identification of the user or the access to the secondary identification parameters database fails to confirm identification of the user.
