SmartPay at the Metro

Quite often there is a line of people wanting to buy a ticket for the Metro in Milan, as well as in other cities. There is no need to waste time queing up. Security is an issue while traveling. Paying with your mobile or card is convenient, however a bit risky taking it out of its safe position to be «tapped» at the Metro.
I warmly recommend a Smart-Watch like AppleWatch, Fitbit or Garmin. I use a Swiss Swatch watch with a Wallet. I configuered my Wallet in the app, added a card with a low credit, and off I go. I put the watch on my right wrist and turn it upside-down. That way I can tap the watch in a quick and discrete manner. Easy and convenient if I am carrying something in one or both hands. Thieves go home!
