Problems solved by technology

[0002] In the prior art, the hand-held intelligent face-swiping POS machine is powered by a single battery, and the voltage of the single battery is low, while printing in the POS machine needs to use a voltage above 7V, which often needs to be boosted to supply power to the printer. The battery supply current Larger, resulting in greater power consumption loss, which directly leads to short standby time, inaccurate battery voltage detection, etc., which brings poor user experience
