So you know how sometimes when you want to buy something, you need to give the person some money? Well, imagine if you could do that really easily with people in other countries too, without needing to worry about different kinds of money and stuff like that. That's kind of what the "Single Euro Payments Area" (SEPA) is all about.
SEPA makes it easier for people and businesses in different countries that use the Euro to make payments to each other. For example, let's say you live in France and you need to buy something from somebody who lives in Spain. With SEPA, you can just send them money using your bank account, and they can receive it in their bank account – pretty cool, huh?
Before SEPA, it was a bit harder to make these kinds of payments because each country used different rules for how money could be sent or received. But now, because of SEPA, everybody in Europe that uses the Euro is using the same rules, so it's much easier to send and receive money in different countries.
But don't worry – you still need to ask your grown-up before you can make any payments, even if it's using SEPA!
