Millions of people use this exact system here in Hong Kong each day. It's amazingly convenient to be able to pay for train, bus, groceries, food in seconds without having to even take the card out of your wallet. People love it here.

But what happens when you have two contactless cards? The system in the article says it won't work if multiple cards are detected... but this would mean you'd have to take the card out of your wallet.

In Hong Kong you verbally ask to pay by for example Octopus (the most popular card) and it activates that option only. So I don't think double charging is possible here.
