The web has becoming a great venue for new ideas on software engineering. My friend referred me to Merchant OS, a point of sale system which utilizes the web for processing and storage of sales information. This web-based POS system is an innovation of the traditional point of sale equipments manufactured for the sole purpose of providing hardware and software which records sales.
Unlike the traditional POS, the web-based pos system offers portability of information. If you are the manager of a store or an establishment, you can easily monitor your income and earnings from the comforts of your own home. How about accepting transactions using your iPhone? It's possible.
