Your card account balance currently requires a minimum balance of at least $10 in order to complete the KYC identity verification process (we recommend at least $30-50 to start with). You must also keep a minimum balance of $10 in your account. When your balance dips below $10 you will need to replenish funds in order to keep using your card.
There is no maximum that you can deposit them – can deposit as much as you want. Each card (virtual and physical) will allow you to spend $5,000 a day, for a combined amount of $10,000 per day in point-of-sale transactions. (Cash or cash equivalent transactions are limited to $500 per day.) These limits apply to the card and may be different for other types of accounts.
