I am not talking about an actual bank. I am talking more like virtual currency. This way on my website I could have a program setup where I can give money and take money. I could give bills that the people could pay with their virtual currency. Basically I could setup a virtual store. I have seen this done and there is a video that shows it. However, I do not know what type of program was used to create this. Please, if you do not know what I am talking about please skip to... 3:49
