If I carry a few contactless cards in my purse/wallet, will I pay for my shopping twice?

As card machines can only ever do a transaction with one card at a time, you cannot pay for the same purchase on two cards.

It’s always a good idea to take your card out of your wallet/purse before touching the reader, to make sure you're using the right card for the transaction.

If you don't take the card out, the wrong card could take the transaction or the cards will clash and no payment will be taken.
