Patent attributes
A method for conducting biometric transactions includes receiving an indication that a user's media is within a detection range of a transaction device. The indication includes an identifier of the media. A list is populated with identifiers of media that are within the detection range. The list includes the identifier of the user's media along with a subset of an overall population of identifiers of media that are each associated with a particular user and biometric identifier. A biometric identifier is received from the transaction device upon being received by the transaction device in an interaction with the user. The biometric identifier is compared to biometric identifiers of only users associated with identifiers on the list of media to identify the user and an account associated with the user. A transaction using the account associated with the identified user authorized and an authorization message is communicated to the transaction device.
