You can send from €0.50 up to a maximum of €500 per transaction per day, and receive a maximum of 20 transactions per day or 30 per month.

To receive a payment instantly, you need to have registered in the Bizum system beforehand.

If the payee is not registered, Bizum will send them a text message informing them that someone wishes to send them money and telling them to go to their bank to obtain the money. The payee has 2 business days to register with Bizum through their bank. When they register, they will receive the funds immediately. If they do not register within this period, the transfer will be cancelled.

The money is not withheld and no charge is made until the payee has registered.
