This is a simple Point of Sale device that would have all the features of a POS point.
It connects to the web application via WiFi and can connect to a bar-code scanner and a POS printer ( Thermal Printer ) and even to a cash drawer.
This is a cost effective and simple to use device that is operated on a 9V battery or an adapter.
The operator can either use the keypad to enter the "numeric item code" or "Bar-code" using the 4 X 4 keypad or use the bar-code scanner for the data input.
He can use the key combination of the alphabetic characters for example:
"A" - Accept Entry
"B" - Bill
"C" - Cancel
"D" - Delete
