The Mi POS application uses NFC phone hardware security and card reader features, enabling mobiles to function like POS machines to make electronic sales simpler for small business owners. The Mi POS is so intuitive, it requires nearly no marketing or user educational efforts. It reduces SME investment in both hardware and software. It is safer than QR code payment and very easy to setup: just complete certification to start receiving money. Mi POS adopts a simple design language with the most important information at the center of the screen. When a card is swiped, the interface changes to help confirm the purchase, greatly improving the user experience.
