These days you don’t need any of the above to unlock a hotel room, buy a mojito or snap a vacation photo. All you need is, well — you. At hotels like Alma Barcelona in Spain, a scan of your fingertips opens the door to your room. At Ushuaïa Ibiza Beach Hotel in the Mediterranean, you can buy suntan lotion and a sarong with a tap of two fingers.
