What are IBANs and BICs?
IBAN stands for "International Bank Account Number".
You can use the Lydia IBAN to transfer money from your bank account to one of your Lydia accounts.
BIC stands for "Bank Identifier Code".
Banks use BIC to identify which bank will process incoming transfers and credit one of your Lydia accounts: Lydia's banking partner Treezor in this case.
The issuing bank may request a BIC when you add the Lydia IBAN to your beneficiaries or for immediate transfers.
