The actual money transfers (the €5 you paid at some shop from your account to the pin terminal vendor, and the hourly or daily total for that shop from the vendor to the shop's internal account) take place hours after the fact.

So for all parties involved it seems instant, but technology wise it's still more or less batched, but seems instant based on trust.

Of course in The Netherlands, we have SEPA Instant Payments now (based on but not entirely the same as the European IP scheme). These are actually instant; when you pay, account balances of you and the creditor (at the other bank) are updated within 5 seconds.
