As long as the deposit is more than £150, yes, you can!
We assume that charges from hotels or car rental agencies over £150 are deposits.
As such, we treat these transactions differently as we don’t capture the payment from your payment card straight away, so Curve effectively acts like your credit card would.
However, Curve can’t distinguish between deposits and normal transactions, so for amounts below £150, Curve will always process the transaction, much like if you paid on your debit card.
