How ATMs work

Hi everyone!
I have a trivial question about how ATMs work, in particular; how does the ATM work in relationship to updating the withdrawer's account balance? 
When someone withdraws the money, is his/her bank account immediately updated (real-time), or are these transactions being stored in the general ledger and then the system runs a batch process to update the respective bank's accounts?

Many thanks in advance
