Cards with contactless payment functionality allow consumers to make payments of up to £20 simply by putting cards within 5cm of a reader.
The bank said there is a danger that money could be taken from the wrong card if the card being used is not removed from a wallet to make the payment. There have been cases of people rubbing against readers and making payments by accident.
According to The Telegraph, the bank wrote to customers and said: "…we have made changes to clarify that if you have a contactless debit card you must remove it from your wallet or purse before using it to make a contactless payment."
A bank spokesperson told Computer Weekly that this was purely good advice to customers and did not involve changing any rules: “This was just in case people were not aware that it is better that the card is taken out of a wallet when making a payment to make sure the right card is used.”
Some 5.3 million contactless transactions worth over £39m were made using Visa contactless cards in March 2013 as more retail outlets and transport services adopt the payment option.
