## Description

FingerprintPay is an Android biometric payment bridge and credential manager that replaces manual password entry with biometric verification for checkout processes in compatible mobile applications. It functions as a tool to authorize payment transactions and automate credential entry through fingerprint verification.

The system utilizes hardware-backed security to decrypt stored payment credentials and map biometric identities to encrypted data blobs stored within the device hardware security module.

The project covers mobile payment security and automated credential entry by combining hardware-backed key storage with accessibility services to identify and populate password fields within third-party applications.
