Unfortunately, so many of these armchair experts automatically think that the actual experts are always right, which of course they are not, as @Tilt has already pointed out. Many businesses do not need or have all the interconnectivity except to take card payments, which must have live connections to various banks to determine a person's ability to actually pay the bill. It is and remains a fact many shops and small businesses still retain the ability to take cash and for that purpose a simple standalone cash register suffices and a quick look on Amazon will reveal 20 pages of the things, so why all the silly comments to the post I made mentioning cash. Some retail businesses still go around their shelves with pricing label machines, printing and sticking labels on their items for sale and the cashiers just punch the numbers into a simple cash register and then giving customers the option of using cash or card and then simply telling the register which method was used by the customer. Others like cafés, pubs etc have a limited range of products and so can and indeed many do, have their own dedicated buttons on the till, which the owner programs them with the prices and the register adds up the items and displays the result, so again no need to have online connection, just enough power to run whatever they need to keep operating, which come from solar or wind with maybe battery backup, or even as I have seen first hand, just a small ICE generator or battery backed inverters, which again Amazon has oodles of the things and also standalone chip and pin readers which need to be online can also be purchased from Amazon. So now perhaps, the other armchair experts, (I did check my facts before posting the original post), will draw a line in the sand and let the thread get back to its core topic of the Truth about electric cars?
