Hi,
Auto self check out with cash is not that easy as you think of and so the budget which you have decided must be increased. To accept both card and cash payment by self service will be coming up with multiple user needs which you are not considering at the moment. Lets decide to have a meeting. We will both first come on the same page and then will estimate the time and cost. Although we are 100% confident on it.
Lets discuss.
