The purpose of this capstone project was to design, construct, and test a biometric fingerprint locking system to control access to a set of lockers. This system offers a convenient alternative to traditional locks and makes lockers easier to use. Traditional locks require some type of prior knowledge, like remembering the numbers and how to enter them for a combination lock. This can make it difficult and annoying to try and use a simple locker. Three main considerations were kept in mind during the design process to make this system more convenient than traditional locks: user friendliness, accuracy of identification, and false positive rate. The most important aspect of this project was to make a user friendly system, without challenges and questions. It was also vital to have a high identification rate while the false positive rate should be kept to a minimum, as people should not be “accidentally” granted access to other’s lockers. To solve this problem, the project was based around a fingerprint scanner which was controlled by a microcontroller. The microcontroller was the brain of the system. It sends instructions to the fingerprint scanner, interprets returned data, and controls a LCD display so that the system was more user friendly. This report will discuss the background information needed to comprehend a fingerprint identification system, a detailed explanation of the design requirements, the design alternatives along with why components were selected, the preliminary proposed design, and the design of the final prototype.
