Can I turn off the contactless functionality on my card?
No you cannot switch it off. If you choose not to use contactless you can simply continue to pay with Chip and Pin, however there are many benefits to contactless payments. It's a quick and easy method of payment for transactions up to £30 and there's no need to fumble with cash. You'll be able to pay in seconds and you don't need to enter a PIN.
If you are a Barclaycard MasterCard customer your limit for making contactless payments is £20.
