For those living close to the University of California at San Diego, it would be a safer bet to collect money from an ATM machine, located considerably further. Research studies, held at university, have discovered a method of easily identifying numbers of ATM Pins, through the natural body heat, emitted by an individual. It was found that researchers were able to sense the secret pin number of ATM cards through a thermal imaging camera, without needing to see the user punch in the buttons.
The research helped to discover that if a snapshot was caught, with a heat-sensing camera of the ATM customers transaction, the photographer could easily identify, which buttons were pressed and in what order, depending on their cooling process. It was estimated that if the picture was taken within 10 seconds of the customer leaving, it has an 80% success rate. The buttons of the ATM machine also play a great part in the act, since plastic buttons tend to contain heat longer than metal ones; thus, making the theft easier.
