I’m back! My FYP overview

Yes I’ve found time to write. At long last! It’s been an intense few weeks. I can safely say I had no idea that would be as tough as it would be. I’ve time to do things for just me again.

I am of course talking about what every 4th year at my University must take part in. A two semester long, put 3 years of teaching into practice, give it everything you have, all out, Final Year Project. The project we spend from the first semester of first year thinking about, right up to even after we’ve started. It’s a project that defines our worth of ability and where our curiosity has buried it’s face. All is our own work and for the vast majority of us, are ideas we picked from our own weird factory of imagination.

For my FYP, I built a secure Peer to peer money transaction system that used NFC, QR and SMS to make transactions happen. The project consisted of an app and 2 servers written in android and php.

Users could opt to sell and item. They would fill out a form and add an image of the item. The app then sent the encrypted information via HTTPS post where a server saves the item information (only enough to preform a transaction later) and have an SMS code generated and sent back to the user. The the user could display the item and anyone wishing to buy the item. They can then scan the device using NFC, scan an encrypted QR code or, text an SMS code to the server. All of those methods are just ways of connecting buyer and seller and the three will preform the transaction in the same way regardless of method.

The project included an SMS server, QR reading in threads, my own design patterns and lots of scripts and small concept classes to show off. A lot was learned in Android and PHP and as always I just want to take that code out, class by class and break it down here.

It was an amazing push and really took a lot of time and effort. It was a journey and race that made the degree feel earned in one year alone. It taxed in as many places as it could and made project management a delicate thing.

While the year isn’t over, there is time to check in and write a small blog to talk about it. It was bursting with features, some Android, some PHP, both will be talked about in their own posts as there’s quite a lot to most of them. It was a project that made a lot to share with you
