Sorry for being dense, but the other day I used one of these machines with a friend and I am confused as to how they work. With the machine at my Natwest I put the cash/cheques in, it counts them, tells me how much they are worth and gives a receipt, simple. This machine instead spits out an envelope that you have to put the cash/cheques into and tell it how much they are worth, then feed in said envelope, but how does that work? the must be dozens of envelopes inside the machine and they have no identifying marks :S
