Actually contactless payments are more secure than you think. In some cases they're more secure than Chip&Pin and especially magstripe.
Contactless payments make a one-time transaction with the merchant. They cannot bill you in the future if you use contactless.
The only information you can get from a contactless card without being an actual authorized merchant is the card number and expiry date. Nothing else. Those details are pretty much useless without your name and the CVV code.
Compare this to Magstripe, which gives away all of your details permanently to the merchant, or chip&pin which can also be used to authorize future payments, not just one-time.
While I'm an advocate for cryptocurrency payments, the FUD around contactless is irritating. Contactless payments are actually closer to cryptocurrency payments than any other method, simply because they're one-time authorizations.
There have been no known cases of contactless fraud in the UK, it's practically a myth. If you're seriously concerned, all you need to do is get an RFID-proof wallet, I believe you can even just line your wallet with tinfoil and it becomes practically impossible to grab any details.
Disclaimer: I do not work for any banks, VISA, or Mastercard. I pay for almost everything online with cryptocurrency where possible, however in-person almost everything is paid for with my contactless cards. In the years of me having several contactless cards, with a normal leather wallet (not RFID-proof), I have never experienced any form of fraud on those cards. Even when going through busy areas such as Manchester Picadilly and London Victoria/Euston.
