How Can I Protect My Cards?Ĭontactless cards use radio waves which can be blocked by metal, such as silver foil. But if you don't spot unauthorised payments in your statement and you don't query them with your bank then you will never know if money has been stolen using contactless payment. One victim saw a payment to Uber for £30 and had never travelled using Uber before, so after spotting this in his bank statement he contacted the bank and was able to get the money refunded. You might not even notice them on your bank statement, or if you do and don't recall spending the money you might put it down to forgetfulness or just not recognising the confusing company names used in bank statements. However, smaller payments, such as those under £30, look far less suspicious and aren't flagged up. If your bank detects that payment is out of character compared to your usual spending habits then there's a chance payment will be rejected and the bank will notify you.
