A mPOS ( mobile point of sale) is a smartphone, tablet or dedicated wireless device that performs the functions of a cash register or electronic point of sale terminal (POSint-of-sale terminal).
mPOS allows service & sales industries to conduct financial transactions in place, improving the customer experience and freeing up valuable real estate that would otherwise be dedicated to a POS countertop. It can be cost-effective, allowing a small business owner to conduct transactions without having to invest in an electronic register or pay someone to support the software. Any smartphone or tablet can be transformed into an mPOS with a downloadable mobile app
