摘要：The proposed design and implementation create an automated safe-keeping machine which acts as Paper Currency Sorter with Fingerprint Access Protection for Ethiopian SME’s. It will help them lessen their worries every time that the store will be jam-packed with customer. Since it is operated automatically, everything can be done smoothly and will definitely make them worry-free from any thieves because it has a special feature of registering your own fingerprint for access protection. This study will sort out money paper currency according to its color (value). It will also have a safety lock that can only determine the fingerprint of the owner. The study considers banknotes that are currently functional, i.e., 1 Birr, 5 Birr, 10 Birr, 50 Birr and 100 Birr. This design is strictly for sorting money and safekeeping. This design is not a fast paced sorter, and its precision is not perfect when it comes to the last paper bill to be sorted. The device will receive an error if the wrong value of money is sensed at the color sensor.
