However, many traditional companies and existing shopping places, like vendor machines, car parking, and corner shops still need manual selections and cash payments due to different aspects of factors. Thus, buying and paying products or services anywhere is an important research topic in e-commerce. In this thesis, a standardized product and service representation is explored, such that there is a standard gateway to any product and service so as to enable shopping and obtaining services anywhere. The proposed approach to a standardized product and service representation is to store URL with UNSPSC integration through QR Code. Based on this approach, the related mobile product purchase and payment through QR Code mechanism is proposed and can be implemented in the proposed architecture.
