It may be arduous to get rid of your old equipment because every single IT asset may store a lot of sensitive information on it, but what happens to those POS machines at the end of their useful lives? Everyone has swiped a personal credit card into a point-of-sale machine, or at least you have seen one of these POS machines in retail locations, restaurants, etc. They can be like a whole terminal with a cash register, display monitor, or a small device that would be thinner than your smartphone. Even when there are tons of different POS systems out there, all of them will keep your card data secure. The point-of-sale terminal, also known as POS, is where credit or debit card payments are made and processed.
