Card machines, card readers, PDQ machines, terminals… whatever you call them, they all accept card payments. But ask yourself, where do your customers expect to pay? Countertop card machines are used by retailers, hotels and salons that have a fixed sales point, like a till. They’re extremely reliable, as they use wired internet or a phoneline to connect. Restaurants, pubs, and any business that take payments across their premises will use a portable card machine. They connect with Wi-Fi, Bluetooth, and in some models 3G, so they can be carried from table to table and used inside and outside. For businesses like food vans, market stalls and taxis, it makes sense to have a mobile card machine. These use GPRS to accept card anywhere with a mobile network.
