Design and development SST Prototype for Yemeni paper currency

Self-service terminal equipment generally, compose of group of integrated systems, which operate together to offer services to human in the economic aspect. The conception of the self-service store terminal equipment facilitates person's life, greatly. The self- service terminal equipment that exist in Yemen are rarely found, because of their extremely expensive cost. Additionally, that material can't deal with all denominations of Yemeni paper currency; just two denominations can be treated. The proposed system is a Mechatronics' system which typifies a prototype of SST equipment which is able to arrangement with all denominations of Yemeni paper currency. The principal function of the proposed scheme is building up an SST prototype with simple social system which is able to recognize and detect four denominations of Yemeni paper currency (1000, 500, 200 and 100 Yr), then store them in the specified box for each denomination. The proposed scheme is composed of four integrated systems as work together concurrently. The entered paper currency is fed into the detection place to be determined whether it is fake or genuine, then if it is genuine, it will be recognized to identify its denomination, finally it is stored in the specified box according to the currency denomination. The identification scheme has been designed to distinguish the dominant colour in each denomination using color sensor, while the detection scheme is designed using the UV - light detector. The developed system has been tested using 10 samples of each denomination for checking the accuracy and speed of operation. The prototype has achieved a high accuracy with short time of processing.
