I use 3 iPads 1 as cash register terminals with Square Register. Recently I discovered a new, similar App called Breadcrumbs. By using this App I could be saving a few $ on credit card processing fees, but......... its only compatible with IOS6 which Ipad 1 will not accept. Now in order to use Breadcrumbs and save money, I might have to spend money and invest into new IOS6 iPads. This, to me is a misnomer, but I seem to have no other solution to this. Unless I can somehow install IOS6 on Ipad 1. Is this possible at all?
