In this paper we propose an implementation technique for coffee vending machine with the goal of getting recharge option for customer using fingerprint-based authentication. We implement the proposed design based on Advance Virtual RISC (AVR) microcontroller. The circuit is tested and compared with the existing embedded technology. Among the various biometric traits (e.g., face, iris, fingerprint, voice), Fingerprint-based authentication has the longest history, and has been successfully adopted in both forensic and civilian applications. Advances in fingerprint capture technology have resulted in new large scale civilian applications. The purpose of this article is to give an overview of fingerprint-based recognition and discuss research opportunities for making these systems perform more effectively.
