Chaos data server down?

[Hacchan]

If only stuff was so simple than a simple confirmation ... i suppose that you have always enough currency just in case ATM system is down ... yep some credit card need some check within your bank to allow you to do an operation.

And what i said is still valid, a bank doesn't need a constant online connection your credit card and flow different amount of data between the card and the bank when you have it on you or when you're using it to buy anything through cashier or online. It literally is just a code that it send to the bank to confirm that you valid the payment and the only check the bank does is if you have the fund or can go in the negative for the month.
The system needed is way lighter and require less power, it's not 'simpler' it still have to do that sort of computing multiple time through the day to multiple location but the system remain just a short back and forth.
