The Challenge of NFC for the DoD
NFC access card technology, via smart phones, like the Blackberry and iPhone. NFC is near field communication and is essentially two-way RFID, or radio frequency identification. NFC key cards are already in use in the hotel and airline industries, with downloadable room keys and boarding passes. Experts believe that eventually driver’s licenses and passport information will migrate to the NFC platform, but currently, there are too many problems with issuance, interoperability and security, that must be resolved first. One major issue for NFC-enabled mobile devices is that older cell phones do not have the installed chips. Existing smart phones without embedded NFC readers could work via Bluetooth tethering or a USB port.
The DoD put out a request for information in September of 2010, to start looking at NFC, to replace its Common Access Card and government employees’ PIV, or personal identity verification, credentials. Used by three million people for logical and physical access, the DoD CAC/PIV smartcard would be a big boon to the winning developer of the chip technology contract. The DoD is considering adding global payment, ATM access, and management of public transit service benefits to the card’s functionality. The DoD would also like to develop a debit card for military personnel, to be able to buy groceries both on and off base.
NFC is divided into two camps, open and secure. Open NFC allows for checking into hotel rooms, stores, or flights. Secure NFC enables financial transactions, whether through NFC access keys or NFC-enabled smartphones. The former can be developed much more rapidly than the latter because of the necessity of multiple layers of security and the complex nature of creating data protection software. Security is obviously the biggest concern for the DoD. Because of the many platforms and systems that support NFC, the potential for hackers and cyber-terrorists to develop viruses and malware is great.
Another problem, with NFC-enabled smartphones, is access control. PIN numbers and pattern codes for locking the phone are common, but the mechanism is usually optional. Any NFC mobile device approved for military use would need additional security layers. Some solutions to this are one-time passcode generators, biometrics, and GPS location tagging. The cameras on smartphones could be utilized for facial or iris recognition or fingerprint swiping. The phone’s GPS technology could flag fraudulent activity from individuals attempting to gain access from a computer that is far removed from the mobile device.
The rate of innovation for mobile apps is a further vulnerability in security. New versions of software are released at a frenetic pace and present problems for organizations trying to keep up. Imagine deploying and maintaining the technology over an organization the size of the Department of Defense. Whether the DoD goes with NFC-enabled smartphones or NFC access keys, it will certainly be a challenge. “>The U.S. Department of Defense (DoD) is considering replacing its Common Access Card with NFC access card technology, via smart phones, like the Blackberry and iPhone.

Software Development Is All About The Development Of Computer Programs With Its Documentation
The era we live is indeed computer based and of course to run the computing machine, it is essential to have software installed in it. A lot of people intend to get the software developed and with this in mind, it is obvious that software development is a fundamental, practicable and commercial process.
There are three types of software:
Custom- These programs are made for specific people or company or an organization.
Generic- These programs are commonly made for all people or an organization.
Embedded- These programs are made for the hardware installation that can be used for different purposes etc.
Problems With Software Development:
There was a lack of data for the development of software and no good way for the productivity measures. The communication gap between customer and developer can also create problems. There is no systematic approach in the development of the same and has little emphasis on the maintenance. There are no complete software testing and implementation procedures available that can help to make it good. Software development tools and magazines are used to solve this problem.
Solutions In Software Development By Software Engineering:
There should be modular approached, divide and conquer rule, high Cohesion, dependant Modules and Low Coupling should be used. Constantine law that involves cohesion and coupling should be following. There will be fewer bugs by using modularity
1. Algorithmic approach
2. Analysis and design
3. Object oriented concepts should be used. Its benefits are long term
4. Developers must work closely with users
Software development plan is concerned with all aspects of software production. Software engineers must use a logical and organized approach to their work and use suitable tools and methods depending upon the problem to be solved, the development constraints and the resources available.
Following are the steps involved in software Development Company that measure metrics.

1. Understand The Environment
2. Understand The System They Could Build
3. Object Oriented Methods
Steps involved in problem solving:
1. Specify The Solution
2. Formulate The Problem
