What an account looks like
A UK account has an account number and sort code. An EU account has an IBAN and BIC. Some accounts also carry virtual IBANs, which are what you send money from on international transfers. Every account reports two balances: the ledger total, and the available balance that can be spent right now. Show the available one to the customer. Accounts with several wallets break the balance down per wallet. Not every account supports every operation. Checkaccounts[].operations in
program capabilities before you show a block, unblock, or close button.
