Electronic Point of Sale System (ePOS)
Application Note
Overview
There is a clear move in the industry to employ electronic point
of sale systems which enables faster service and increased
efficiency in product management. Popular ePOS solutions
include the following:
:Secured Data terminal
:Point of Sale
:Bar code scanner
:RFID reader
:Electronic Shelf Label
:Contact based and contactless Smart Card Reader
:Magnetic Card Reader
This application note illustrates the development of an
Electronic Point of Sale (ePOS) system based on the ARM
Cortex Ax processor.
Electronic Point of Sale (ePOS) Architecture
The key feature of a POS terminal revolves around the reading
of contact and contactless cards while securely transmitting
the information, including the transaction, to a server for authen-
tication and approval. Today, most POS systems transmit
transactions to their network over a tethered connection but there
is a growing demand for a portable / mobile solution. The optimized
device is suitable for markets such as retail, healthcare, hospitality,
education and more.
