Mobile Point of Sale (mPOS) is using mobile devices, such as smartphones or tablets, as portable and wireless point-of-sale terminals in the retail industry. This technology enables retailers to process transactions, accept payments, and manage sales on the go, providing flexibility and convenience. mPOS systems typically involve a mobile app or software that connects to payment processors, allowing retailers to accept credit card payments, digital wallets, and other electronic payments anywhere in the store or off-site locations. Adopting mPOS enhances customer service, reduces checkout times, and allows for more dynamic and flexible retail experiences.
