1. A non-transitory computer readable medium comprising executable code, that when executed by one or more processors, causes the one or more processors to:
receive, at a reader device from a memory of a portable credential device of a user, at least one of a first image of the user or a first representation of a face of the user;
if a first image of the user was received, then generate, at the reader device, a generated representation of the face of the user using the first image;
capture, at the reader device, a second image of the user and generate a second representation of the face of the user using the second image;
receive, at the reader device from the user, an authentication factor;
determine validity of the authentication factor;
determine, subsequent to determining the validity of the authentication factor, a confidence of a match between the second representation and at least one of the first representation and the generated representation; and
if the confidence is below a minimum threshold indicating an insufficient match and the authentication factor is determined to be valid, at least one of supplement or replace at least one of the first image or first representation with the second image or second representation, respectively.
