Security deposits for hotels or car rentals can be paid with your Pleo card.
The transaction will appear under Expenses as "pending" when the merchant initiates the charge. This means the amount is reserved but not taken from your Pleo wallet yet.
If the merchant claims your security deposit, the transaction will settle and the funds will be taken from your Pleo wallet balance.
If the merchant releases your security deposit, the transaction will disappear from your Expenses and the reserved funds will be released to your Pleo wallet balance.
