Speaking as a citizen of a country that isnít ready to let go of the penny, Iím not sure everyone is ready for a cashless society. Ready or not, South Dakota School of Mines and Technology (Mines), and possibly all of surrounding Rapid City, are about to embark on a pilot program for a cashless society in partnership with Nexus USA's Smart Pay system.
In place of a card or some other form of ID, the program uses a system called Biocryptology. The biometrics technology uses a radio frequency to penetrate down seven layers into the skin on a userís index finger to identify a valid user. The Smart Pay system even checks for hemoglobin in the blood of the finger to determine the user is alive.
