Rather than carrying around cash and cards, just tap your phone to pay. Currently, the three most established systems are from

            Apple
    , 
            Samsung
     and 
            Google
    , although some wearables from brands like 
            Garmin
     and 
            Fitbit
     also offer their own payment systems.
