Key card with hole punch for the Infinity?

[bluecruise1]

Anyone know if I can punch a hole in the card key for the Infinity?  I usually bring my own lanyard and a hole punch so it's easy to carry my card key around but last October on Royal Caribbean Anthem the hole I punched ruin the key's ability to open my cabin door 😞  I'm sailing on the Infinity in July and want to know if I need to get a plastic case to hold my card or if I can use my hole punch.  Thanks for the help!

No need to bring your own hole punch, just go to Guest Relations and they will do that for you.  They know the correct area to punch so your cardxwon’t be disables.

The cards on Anthem are RFID cards; using your own hole punch, you hit the chip. Celebrity seems to be switching to these cards on several ships. I’m not sure about Infinity, but if you do encounter such a card again, just bring it to Guest Services; they know where the hole can be punched. (I had no problem doing that on Anthem.)
