ATMs are using GPS because of the timestamps simply because atomic clocks are very expensive to install on each ATM. Personally, I find it interesting because they found a use of GPS signal other than positioning. However, I felt a certain degree on uneasiness for our increasing reliance to GPS signals in many of our daily activities, considering the planned expansion and creation of other GNSS (GLONASS, Galileo, China and Japan) are far from operational.
