Tablet VS Android POS all-in-one

Single machine cost : There are many external devices for external printers, so the natural cost will be high. However, The POS all-in-one machine is more like an iterative update of the machine, integrating the display, printer and cash register into a simple POS device with hands, which greatly reduces the cost.

mobility : external printer mobility is poor, because in order to achieve an external printer to print need tablet, need a printer, may be a cash register, it is appropriate for a fixed space, is not convenient to carry, dismantle, reassemble, however, the all-in-one pos only need to carry the machine itself ,which is very flexible and convenient

The proportion of space occupied：Compared with tablet, POS all-in-one machine has more advantages. As mentioned above, tablet requires more auxiliary devices, so the space occupied ratio is larger, while POS all-in-one machine is small and lovely.

Easy to operate：The assembly and operation of a tablet external Bluetooth is very complicated, and many users say they don’t understand it at all,even some LAN connections also require the same network. However, our handheld POS terminals have a variety of networking methods, such as wifi/ dual card/dual standby/Bluetooth, so we don’t worry about the network at all.Besides,there is no tedious assembly or complicated operation for installation and use.

Battery loss：For external Bluetooth printer,both the tablet and the bluetooth printer need battery power, which means they need to charge two batteries at a time. either one battery is bad,,then the machine can’t work, but the Android POS all-in-one machine only needs one battery to run.
