I literally would close my account if the bank didn't offer contactless. It's so much better. To answer your concern - the only way for anyone to "swipe" your purse is to have an authorized, authenticated terminal which can communicate with your card using the proper key from the bank - which means that the terminal would get invalidated by the bank straight away after people started reporting fraud. Contactless cards literally won't surrender their information to regular NFC readers. But even assuming they could - the most you can be charged is relatively small amount, and only 5x a day until you have to type in your pin - and if that happened your bank would refund you instantly. So seriously, I can't imagine not having a contactless card.

Unfortunately that's only true until the next vulnerability that allows theft via NFC on a mobile device. There has already been one, there will almost certainly be another.

> "With just a mobile phone we created a PoS terminal that could read a card through a wallet," said Martin Emms, lead researcher on the project. "All the checks are carried out on the card rather than the terminal so at the point of transaction, there is nothing to raise suspicions. By pre-setting the amount you want to transfer, you can bump your mobile against someone’s pocket or swipe your phone over a wallet left on a table and approve a transaction. In our tests, it took less than a second for the transaction to be approved."

Absolutely - but that still flags a terminal for review and will get it blocked. There does not exist any vulnerability that would allow you to clone NFC cards, which has the biggest potential for abuse. And again, even then - contactless cannot be used to take out any cash, so it's not an attractive target for thieves. What are they going to buy with a cloned NFC card(if they could get one)? Lunch?
