Could Apple sell this as a cash register for businesses such as cafés, small hotels, and such?

The format is right, it is stuck to a power cord, it would integrate with iPhones that waiters use to take orders, it apparently has a USB-C connector perhaps for a receipt printer, it has Bluetooth and WiFi of course. It can control the music and security systems and lights in a business locale.

Most importantly it has easy separate login for different employees.

And the price is just right.

Is there any important detail I haven't thought about?
