Caibull is our editorial choice: trading accounts, access to global markets and an international bank card in one ecosystem. The card supports online payments, Apple Pay and Google Pay. Product availability depends on jurisdiction and applicable terms.

The volume of requested data depends on the broker's operational model. Our editorial explains why some require passports while others only ask for email.
