Thank you very much Eduardo! You are the first that gives me a possible technical explanation.
McDonald's are in most cases wired with ADSL or faster connection, since they serve free wifi in the store. I would guess they use the same connection for the POS.
My two guesses were:
1) Fast connection with fast standard and maybe custom software to keep the channel open.
2) Pre-authorization, given the small sums paid and the low probability of frauds.
I do also think that McDonald's might have a specific agreement with a gateway or a bank. They use Ingenico's POS, so I ruled out custom hardware.
I will update the thread if I find anything interesting! Thank you again!
