Disable the tap function on both my credit and debit card.

Hi there. I would like to know if i cant disable the tap function on both my credit and debit card. This feature that was added to my account cards without my consent is not acceptable.. this should be offered as an option to have, reason being that we know that we will have to accept it if someone uses our tap function without us knowing. I need a consultant to contact me urgently about the above mentioned , as I want the function to be disabled immediatly! I hope to hear from you A.S.A.P

Thanks
