Refund via Paypal

I set up a separate bank account for supplying the PP. account. It's a savings account not linked to any of my others. In it is a small amount of money to cover any on line purchases and can easily be topped up if need be.
If it's hacked ( I hope not ) then only a small amount of money is compromised.

I've had refunds via Paypal. There's never been a problem. Someone knowing your bank account number and sort code can pay money in but they can't take any out.

My worry is because PayPal is linked to our bank a/c and you do not have to do anything other than click the button - and bingo! - money is gone!

Why the worry about bank details? Our sort code and account number - plus a specimen signature-has been on every cheque we have ever issued.

I've used PayPal for years - never had any problem with either buying or selling. Surely if you're willing to give your bank details direct to the company it amounts to the same thing as PayPal having your bank details. I would have thought using PayPal would be more secure.
