Help if I should cancel my card?

So, today, namili ako ng items sa isang store. paid using tap to pay. tapos after a few seconds after magsuccess yung tap payment, hiningi sakin yung card ko kasi kelangan pa daw yung number. so binigay ko naman kasi minsan ganun naman ginagawa(pag hindi tap to pay). then nitong paguwi ko na narealize na tap to pay na yung ginawa ko, hindi ba dapat na wala na yung extra step na need kunin yung card ko?

Saw the guy look front and back of my card. I have sticker on top of my cvv naman, though exposed yung expiry date and card number. Should I have my card cancelled or nothing much to worry naman yung gantong case?
