Multiple NFC cards in one wallet?

Question

Payment cards

Let's say I have several cards in my wallet that support contactless payment technology. In the store, I put my wallet on the terminal. What card will the money be debited from?

Answer 1

With the one that will be more sensitive, less brake (chip in the map). In general, they are not recommended to be worn like this - so that they can be read openly.

Answer 2

With none. The payment terminal will reject the transaction, as stated in the documentation.
