Money/ATM help

Hi I am trying to create a program that can check the amount of "money" on a floppy disk and have it so they they can sell or buy to gain/lose money but I don't know how to make it so that a computer can check the values on a disk and how to edit them either any help would be great.

Not so descriptive, but yes the file system is a great choice in this usage.

You NEVER want to store money on a disk. The reason is because anybody can give themselves a ton of money by editing the file it is stored on.

We're currently discussing systems for doing that here.
Feel free to join the discussion and add new ideas.

I'm working on just this right now. Of course, all money is stored in a database/server and only certain computers can access that. So basically, here's how it works:

There's a server that always listens for transactions from the certain computers that can access it and when it gets something, it comes in three parts: Part #1 - Person ID Code | Part #2 - Mode(0 or 1, 0 is a deposit and 1 is a withdraw) | Part #3 - Number of money. The people on my server get a credit card that has an 8 digit code so nobody could ever guess the code. If their credit card gets stolen, that's their fault, so I'm not worried. Now currently, the server is half finished, it works though, and the ATM is completely finished for the most part but then I still need to start on the trader and the trader sells or buys stuff to/from people and the people's money goes to the seller's credit card or to the buyer's credit card. There would also be three rednet messages in this too: Part #1 - Seller ID Code | Part #2 - Buyer ID Code | Part #3 - Number of money.

So that's how my system is working.

i wouldnt use cards at all, unless i would like to take part in some hack warfare :3

Team Econ/HBS wants to use credit cards and personal passwords for additional security, just as in real life.

Saunds cool but can u plz shere the code i haw looked at a couple of simulars 1 but i haw newer manage to run them

achevement get!
bump a ancient thread
you would need an authentication server to do this securely

I wouldn't call this thread ancient. However, it is a good idea to accept that if someone hasn't posted the code for their secure banking system, they have a reason.

It is also good practice to use the concepts discussed here to design your own system and begin coding it, if you are not satisfied with any ready-made solutions available in the Programs forum. When you run into an actual difficulty (not just "I'd rather someone else coded this for me" itis), please feel free to ask for help with the specific problem you're having.
