Sierra Wireless AirLink® FXT EDGE
Point of Sale (POS) application based on Sierra
Wireless AirLink FXT Hardware & OpenAT ™

4. Developer Day, June 2013 4
Description of the application
The goal of this application is to migrate payment terminals,
vending machines or electronic banking servers using traditionnals
PSTN or ISDN lines available on X25 network to new IP
connectivity (ADSL / GPRS) and reduce the operating costs of our
customers with offerings SIM package and IP subscription.
Main objectives of the application:
q Minimize the cost of phone communications for POS systems
or POS Banking Server using another network than X25 to route
the data to the Bank
q Boost the transactions and streamline the checkout process
q Provide a backup solution if ADSL line falls.

How to develop the application
Such applications requires skills in developing embedded systems
and server development.
To develop this application and meet the needs of our customers
we used a Wireless AirLink® FXT EDGE modem and standard
development tools provided by Sierra Wireless.
For the server part we have been supported by our parent
company Lyra Network which provides us the necessary ways for
the recovery of data, information management and routing flow to
the bank using leased line, IP or X25 connections.

How to develop the application
To develop this application we need 5 main functions:
q Retrieve Payment data from a serial or Ethernet link & Integrate the
protocols needed to dialogue with POS machine or Server (PAD &
Telnet);
q Integrate our own stack for all encryption security protocols (SSL
V3.0 & RFC1086+) and the management of SSL certificates up to
4096 bits according to the GIE French CB organization for approval
q Integrate a GPRS / EDGE Backup Feature
q Including a secure and proprietary system to update, manage and
setup the AirLink FXT remotely and discuss with LYRA servers in
order to provide information as the CSQ level, OS & application
versions, ICCID & IMEI numbers…
q Manage a storage space for configuration and SSL certificates.
