63426 POS system

I'm looking for a POS system which is quite simple and straight forward. Also I want it to be exclusive to me. I can find a free POS system at downloadcom but since I'm going to install it to my client, therefore I do not like it to have other developers name. This POS system must be compatible with any accounting software or has a built in accounting system and must be able to integrate with barcode scanner, cash drawer, receipt printer etc. I saw one freeware at downloadcom but since it has bear the developer name, so i don't like it. One of it that attarct my attention is binaremacom
