POS

POS (Point of Sale) is a system that records and manages sales information at the moment of transaction. POS terminals at supermarket and convenience store registers scan product barcodes, read prices, and aggregate sales data in real time. They support inventory management, bestseller analysis, and automated ordering.

With QR code payment adoption, POS-QR integration has accelerated. In store-scan mode, a POS-connected scanner reads the customer's phone-displayed QR code for payment processing. POS integration automatically links product sales data with payment data, eliminating manual entry errors.

Mobile POS systems based on tablets and smartphones (Square, Airレジ, Smaregi) have made low-cost adoption possible for small shops. While traditional POS terminals cost hundreds of thousands of yen, mobile POS starts at tens of thousands with a tablet and card reader, driving QR code payment adoption.
