Can hotel key cards be washed?

Hotel room cards can be washed. Today's room cards are generally sensor-type room cards. They seal the chip and antenna in two layers of PVC materials, and then laminate and punch them at high temperature. If it is made into a room card in the future, as long as it is not intentionally bent to damage the chip or the connection between the chip and the antenna is disconnected, which affects card reading, washing will not affect the normal reading and writing of the room card
