I have worked on various systems that use web services and proprietary software to communicate in real time across the internet or protected VPN’s.

For a London based company I completely re-wrote a mobile top up system in Flash that used web services and there own wrapper to communicate in real time across a network.

The project was run on a touch screen which allowed users to select the amount they wanted to top up, communicate with the server ensuring that a successfull secure handshake took place debiting the money from the machine and then the system either sent a SMS message to the handset, printed a voucher or displayed the code on screen to manually top up.

This project was quite complex as alot of error trapping had to take place to ensure that the transaction went through without fault. It used built in printers to print tickets and had various traps to ensure the customer could top up securly. I enhanced the interface with a new phone design that allowed users to easily interface with the system. Entering details as they would on a mobile key pad.

Lots of Actionscript programming work involved, but a good fun product to produce!
