Aspects described herein may allow for authentication of smart card usage. A server may receive, from a first computing device associated with a first user, a delegation request to delegate an authority, to a second user, to use a secondary card associated with an account belonging to the first user. The first user may hold a primary card associated with the account and the delegation request comprises one or more limitations on the authority. The server may also receive, via a sensor on the secondary card, first biometric information associated with the second user. The server may authenticate subsequent transaction requests based on the first biometric information and one or more limitations. In this way, the system may provide account holders with the flexibility to authorize other users to use the account while minimizing the risk of being exposed to fraudulent requests.
