Abstract: In some implementations, a physical medium may include a fingerprint scanner, one or more memories that store fingerprint data and a PIN, and one or more processors. The physical medium may receive power from a terminal that is in communication with the physical medium. The physical medium may scan a fingerprint using the fingerprint scanner and the power received from the terminal. The physical medium may compare scanned fingerprint data, determined based on scanning the fingerprint, and the stored fingerprint data using the power received from the terminal. The physical medium may determine that the scanned fingerprint data sufficiently matches the stored fingerprint data based on comparing the scanned fingerprint data and the stored fingerprint data. The physical medium may transmit the PIN to the terminal based on determining that the scanned fingerprint data sufficiently matches the stored fingerprint data.

Abstract: In some implementations, a system may receive, from a terminal, an account identifier, an authentication credential, and a request for data associated with a user, wherein the request may identify requested data items associated with the account identifier. The system may authenticate the request using the account identifier and the authentication credential. The system may determine whether the request satisfies a pre-approval condition after authenticating the request. The system may transmit a first message to a user device associated with the user or transmit a second message to a third party device associated with the terminal based on whether the requested data items satisfy the pre-approval condition. The first message to the user device may request approval to transmit the requested data items to the third party device via the second message, and the second message may enable access to the requested data items.

Abstract: Embodiments consistent with the invention provide a computer-implemented method for determining a credit risk associated with a customer. The method comprises receiving a credit request from the customer, electronically requesting check-writing behavior information associated with the customer, electronically determining the credit risk of the customer based at least in part on the check-writing behavior information associated with the customer, and presenting a determination of credit eligibility based on the credit risk to the customer.
