transmit Visa cardholder data. RadioShack has aimed to achieve compliance with

Visa PCI guide lines – for all Credit Card (CC) information. With this project,

RadioShack will protect its customers’ full credit card numbers by either encrypting

or masking the card number, depending on the need of each group (that is

associated with the company) that accesses, uses, or reports the credit card

number.

Project Abstract This project aims to eliminate system inefficiencies by cross-linking the Test, Parts

Changes, and Problem Resolution information locations. A new feature is added to

this project, which is called “Replication”. This feature has two options, namely,

“Two-way Replication” and “One-way Replication”. “Two-way Replication” helps in

keeping the integrity of the data intact by comparing the timestamp of the existing

data in the server database with the timestamp of the data associated with new

updates from the client to the server database. “One-way Replication” will allow the

client to update the server database with whatever data it has on its database.
