Hi SelvamM,
Thanks for posting 🙂
Whenever you add or edit a card on your PayPal account, a temporary authorisation charge of $1 is made to verify that the card is active and capable of funding your payments. It's essentially a test charge, and it's a standard industry procedure.
So when you add that debit card, you will need at least $1 available beforehand. This charge may take up to 30 days to be reversed but in my experience, it is usually returned much sooner that that.
I hope that helps and enjoy your evening,
Conor
