A retail checkout system includes a mobile point-of-sale apparatus and a server. The mobile POS apparatus includes a wireless communication interface, a display, a battery, and a processor configured to control the wireless communication interface to transmit a login request and to transmit a product code for product registration and to perform a logoff process. The server is configured to perform a login process upon receiving the login request and to generate a transaction data record including the product code(s). The processor is also configured to determine whether a remaining power level of the battery is below a predetermined threshold when switching the mobile POS apparatus to the logged-off state and to control the display to display a power shortage warning if the remaining power level is below the predetermined threshold level.
