NFC AND SECURE SOCKET ENABLED COMMUNICATION SYSTEM

FOR MOBILE APPLICATIONS

Global IT Solutions

PSI collaborated with a SaaS solutions provider in the finance industry to develop an iOS application using NFC

with TCP secure communications.

ABOUT THE CLIENTThe client is a cloud-based SaaS solutions provider for billing, mobile banking, and payments thereby enabling customers to pay, buy, bank, bill, and remit money with a mobile device at the point of sale(PoS). Technology solutions offered by the provider bridges the gaps between mobile wallet and payment solutions at the PoS. It enables banks, financial service providers, mobile network operators and existing payment technology providers to connect with their customers worldwide.

CLIENT’S SERVICE OFFERING

SOLUTION APPROACH & METHODOLOGY

The developed app enables communication with the client server through secured TCP messaging and NFC (Near Field Communications). The system will be used for PoS terminal communications. The features include transfer of funds within users’ application accounts or transfer to PoS merchant bank accounts and other operators aligned to the application. The application also offers features like voucher redemption, bill payment, purchase invoice and PIN change requests among others.

The foremost requirement was to have an iOS app. which can support the growing demand of consumers on Apple devices and can also help in communicating with the server via secure TCP messaging. The communication was required to be executed in a secure environment.

It was also required to be a configurable build for branding purposes using configuration files right at build time without making any changes at code level.

PSI developed the proof of concept (POC) natively using XCODE as development platform, with Objective C as development language. We developed the solution on Model View Controller based approach to ensure reusability with best definitions of all the interfaces, and for branding we used specific property list files. Storyboards with auto-layout based approach were used for UI to ensure that the design works with multiple iOS screens. Core data was used to ensure seamless integration of the client side data layer with UI components.

KEY CHALLENGESThe NFC feature is not comprehensively available on iOS for the general applications

Client wanted the screens of iOS application similar to their existing android application, so the team used storyboards with Auto Layout feature introduced by Apple

They also required automated white labelling which can be configured during thedevelopment process

The communication with server was through secure TCP based messaging, PSI used secure transport API to perform secure connection between server and client

The team developed PoS terminal communication application with secure TCP based messaging

Created secure real time financial transactions using sockets/streams

The second phase included NFC enabled transfers using ACR 32 Reader

ACHIEVEMENTS
