I believe if you book a room at the hotel they'd give you a keycard which you use to tap on the card reader retrofitted into the door to open it.

Similarly, to use the keycards we get in gifts, there needs to be something to read the information contained inside the card - of the item we are getting with the keycard.

As such, could the admins sell keycard readers so that we could all use our keycards? I'd suggest the price of the keycard reader be at least 70k gralats.
