Smart watch. Back of a watch that acts as a wireless electronic pass. A ticket loaded onto a microchip on the watch may be read by holding the watch near to a scanner. A trigger signal from the scanner causes the watch's transponder to send out a signal giving details of the ticket, to allow access to a ski slope for example. The watch's antenna (blue) and copper coil (lower right) can be seen. This Access watch is made by Swatch.
