If your card is lost or stolen you should notify your bank as soon as possible. If anyone has fraudulently used your contactless card to make a payment, providing you take reasonable precautions to protect your card and let your bank know as soon as you realise it’s gone, you will not be responsible for any losses incurred (subject to your bank’s terms and conditions).
I now have a contactless card, and use it that way very occasionally. Normal is still to use the pin. If you have a bank account from which automatic payments are made throughout the month, you need to keep you own account to see what your true (available) balance is : constant small debit card payments make this a pain.My solution is to revert to paying cash - two visits to an ATM a week to log, and little else, makes the job easier.
There was a previous system where you could put money onto a card. But it found no favour and was scrapped. It was based in Swindon. I think the problem was the it was difficult to keep track of what money had been taken from it. I suppose one answer is to have an extra bank account and only put a little money at a time into it.
