POS

POS stands for Point Of Sale. For laymans like me that translates to checkout counter usually. You know the place where someone kindly empties your wallet or bank account with a smile and a "thank you, come again" routine.
Checkouts are very automatic these days, with the items you want to purchase scanned for their bar codes and the cash register automatically puts the right price of the item into the add column and the cashier moves on to the next item to be scanned. Very efficient.
If you have a business that is brick and mortar (actual building, not an online business) then you either already have one of these machines or you are searching for one. How about the Epson TM-T88V? This is not a cash register type POS piece of equipment but rather a printer that prints out receipts once the cash register part has finished adding up your purchase.
This POS item is, for my money, more valuable than the cash register because every customer needs a receipt whether to prove to their business that they actually bought the items or, if by some chance something is amiss, they can return the item to the store and prove that they purchased the item there.
If you have a business or are planning on starting one you owe it to yourself to check these POS items out for you. POS Micro has a wide variety of POS items to choose from so you are sure to find the POS items that you need.
