Leon, Mexico has began implementing an iris scan biometric system from New York-based Global Rainmakers; the system, rolled out across the city, will see the eyes of anyone taking money out of an ATM, paying for items in a store, or simply catching a bus scanned by hi-tech sensors; Global Rainmaker’s CEO says the company has chosen iris scan for its project because “With iris, you have over 2,000 points— With those 2,000 points, you can create a unique 16,000 bit stream of numbers that represents every human on the planet. That provides a reference point that can connect everything you do in all aspects of life, for the first time ever”
