Reasons of why this application was developed

Some reasons for the appearance of this application are described here.

Features

This is a side project of my full-time job and only the features that I currently need in my everyday work are implemented.

Currently only the basic stuff is working, such as:

• Connecting to ATM host
• Showing ATM connection status icon (Offline, Connected, Out-Of-service, In-Service)
• Moving through almost all the basic states (ICC states are passed through as well)
• Showing basic image screens linked to the state
• Checking the Card's financial institution based on FIT tables
• Keyboard shortcuts: FDK (A-I), numeric(0-9), Esc, Enter and Backspace
• Receiving and processing states, screens and FITs (financial insitution tables) from host
• Showing traces in a log area
• Saving ATM configuration data (such as states, screens, FITs, ConfigID, counters etc) and restoring it on application start
• Showing dynamic on-screen data received from host
• Crypto support: PIN block encryption, dynamic key exchange etc. (Triple DES double length key only)
• State Navigator: showing graph of states
• State Navigator: updating screen image when jumping through the states
• State Navigator: displaying state details when state selected
• FITs: showing a table of Financial Institutions

Things to be implemented (very) soon:

• Touch area support (pressing touch areas, not only FDK buttons)
• Auto reconnection
• Saving the image path in user settings
• ICC support

FAQ

What is this about?

This is an implementation of ATM (Automatic Teller machine) simulator, working under APTRA™ Advance NDC protocol.

And why may I need it?

If you are working with ATM processing systems (a.k.a ATM Host - the systems to which ATMs are connected, and which process various messages from ATMs, including financial inquiries) - either developing applications or supporting them, you may need to emulate the ATM messages coming to the host. You're lucky if you have a real ATM nearby, but the chances are that your test ATM may be located on the other floor, or, the company that you're currently working in may not have a real ATM at all. Being fed up with closed-source self-written ATM-simulators, I decided to develop my own stable featureful open-source ATM simulator, which may be available to everyone in the Banking/Card processing community.

The application is ugly.

Yes, I know and I'm really sorry. I'm not a frontend developer (I'm not even a web-developer as my daytime job is related to soft-realtime payment processing, and my native language is C). Obviously, I'm not good at CSS at all, so, if you are strong enough in UI/UX, please, feel free to do something with this. And that. And that as well.

jQuery? Why not React?

To me, React is good for building user-interface-specific applications, while this application is considered as backend-centric (i.e. having tons of the protocol-specific code in the backend). As always, it started as a simple Electron app with "just a little jQuery", but now it's a whole mess of event-handlers and SetInterval functions, that already need to be rewritten. So, if you're brave enough to redesign it all using React, please send me a pull request! ;)

Why not ES6?

I thought of ES6 in the very beginning, but Electron does not support ES6 out of the box, and transpiling with Babel looked as a complete overdesign to me. Again, if you would like to have ES6 in this application, just send me a pull request.

I would like to use the application, but it seems that the feature X, that I really need is not yet implemented.

As I said, only the features that I needed were implemented. For example, all the ATM configurations that I've been working with don't have V-type states (Language select from a card), therefore, these states are not supported by the application. So, if there is a feature that you would like to have implemented, you may create an issue, or just drop me an email.
