Iban cheater?

I sell a laptop on ebay, now I've sent my iban, my name and my bank name to a woman. Now, in retrospect, I'm afraid that they are cheaters. What could theoretically be done with this data? Should I be worried?

Theoretically, the "opposite" could debit from your account, this deadline has been extended by two weeks in the European standardization of payment and direct debit and is now eight weeks for SEPA.

So if you notice an unauthorized debit, then you have eight weeks to get the money back.

The Iban is not really a secret.

On every bill of a trader stands his IBAN, so that his customers can pay the bills.

You can give the Iban to your buyer without any consideration, otherwise he can't transfer anything to you.

However, it is important that you check your account transactions regularly every few days, but at least weekly. If then unauthorized charges appear, then you can book them back

For unauthorized charges even up to 13 months.

No, not if you regularly check your account. Of course you have to give the buyer your IBAN, how else can he transfer the money?

What makes you think it could be a cheater?

You can always return unjustified charges.
