Sending money to other payzy users can be done very easily through the quick actions button on the homepage. Alternatively you can do it through a chat with another user by clicking on the corresponding money icon. You can then enter the exact amount you wish to send and confirm the transaction using your device's biometrics.
Alternatively, you can transfer money to another payzy user through the "Transfer" section in your wallet, where you will be prompted to enter the IBAN and full name of the user you want to send money to.
