If money was the way to pay in the old days, the card is now the most popular paying method. So every decent place selling something is usually equipped with a POS Machine.
Next to the cash register, the POS Equipment is a must have when it comes to selling. If you are opening a new business and are looking for some equipment of this kind, look online! Compare items and find out what the best price is! Find the cash register that you need, then look some more and buy a cash register drawer or tray as well. If you are running a restaurant and need several terminal points, look for some keyboards and POS terminals or displays! Do you want to impress your guests from the ordering menu to the paying method? An electronic signature capture pad and some mini MICR card readers will do the trick. If you want to make it come easy to your employees, make sure you have enough coin trays or even a cash boxes with security lock available behind the counter at all times.
Go online and make sure that you pay the right price for all of these!
