I just got my GXBank physical card yesterday and it mentioned I will need to perform one PIN transaction before can use the contactless feature. Is this a mandatory step or just a suggestive step? Based on real user experience?

Many years ago, when contactless function was just rolled out, this step was needed but now no longer required, we can straight away tap for the first transaction.

My problem is I have few bank accounts that I move money around.  So, in "My Recent Recipients" in my transfer history, I only see my name and not the account number.. so, I can't tell which one is which bank until I click on it    Also, my phone can only show up to 8 transfer history.
