. Softcard Mobile Payment Wallet (NFC, Android, iOS)

Softcard (formerly Isis Mobile Wallet) is a joint venture between

AT&T, T-Mobile and Verizon in the mobile payment space. The system is

based on near-field communication (NFC) technology and allows users to

pay by tapping their mobile device to a payment terminal. Also Besides

payment cards, Softcard holds offers and participating store loyalty

programs which are also NFC enabled. Softcard is location aware, so

that advertisements and offers can be sent to user based on location.

The system also carries a location aware map so users can easily

search for stores to use their cards and offers.

mobile application. Those services include:

1. User Account /preference/security management services

2. Payment card management services

3. Location aware map search/Merchant/Store services

o Designed/Implemented JMS based asynchronous event handling system

with retry, persistence, dead letter processing mechanisms.

o Designed/Implemented high performance, location-aware

advertisement/offer targeting server with criterion rule engine.

o Used GemFire cache to optimize system performance and management

session and conversations.

o As part of continuous improvement, drive the effort of increasing

unit test, integration test and automated test coverage. Lead the

design and implementation of WPS test automation tool based on

Selenium technology.

o Lead the effort of design/implementation of WPS management

console using AngularJS.
