Abstract
A system and method for currency validation of a bank note with a radio frequency identification device therein utilizes a computer, server and communication link and a smartphone including an RFID reader, transmitter/receiver and an internet connection. A bank note is issued with a value, a serial number and a secret seed message that is also saved on the issuer's server. A tamper proof RFID mu-chip is embedded in the currency note and includes the value, serial number, plus the secret message for making a calculation. The smartphone reads the information on the chip and requests an issuer/authenticator to validate the note. The issuer/authenticator transmits a challenge and the mu-chip calculates an answer that is sent to the issuer/authenticator. An approval or disapproval is then sent to the smartphone.
