Just received my new Debit Card and, like the one before, it is contactless. However, the accompanying letter states that "You will need to use your card and PIN to activate this feature." Is that just the first time i use it, or the first time in each store?
You have to use the PIN to show it's yours, just once before you use it contactless. But also every so often to keep it activated. If you use it contactless too many times in a row, it will deactivate until you confirm with the pin again.
